2014 gave us massive debut albums (George Ezra, Sam Smith, Royal Blood) and some great pop records (Ed Sheeran, Taylor Swift), as well as some anticipated releases that failed to impress.

But what releases can we expect in 2015? Read below to find out what albums you can get excited about over the next 12 months.

1. Madonna: Rebel Heart



If there's one thing we've enjoyed throughout 2014, it's Madonna's ridiculous Instagram account. Fans who follow the Queen of Pop will know that she has been working hard all year on her 13th studio album Rebel Heart, while also coming up with any number of amazing hashtags (personal highlight: #cantabitchjustfinishhers**t). Despite the illegal leak of 13 unfinished tracks earlier this month (and subsequent official release of 6 tracks), we are still eager to hear the final, polished product when it comes out in March. If 'Ghosttown' and 'Living For Love' are anything to go by, we're expecting it to be Madonna's best new album in years.

2. Kanye West: TBC



The rumours surrounding Kanye West's seventh album have been almost as outrageous as the man himself. From Seth Rogen claiming West rapped the album in its entirety to him in the back of a limo, to collaborator Malik Yusef comparing the LP to a pair of Timberlands. Rick Rubin and Q-Tip are producing the anticipated follow-up to Yeezus, with West claiming he'd like to have the album out by Summer 2015.

3. Madeon: Adventure



It's the album we've been waiting patiently for since Madeon's storming 2012 dance anthems 'The City', 'Icarus' and 'Finale'. During that time, the French prodigy has worked with Lady Gaga for her ARTPOP album, as well as releasing two new singles 'Imperium' and 'You're On' earlier this year. The latest offerings continues his trademark combination of jubilant beats and cosmic synths which we hope are the main threads going through Adventure.

4. Adele: TBC



After sitting very tight for Adele's third studio album for the whole of 2014, the world is now pinning its hopes on an imminent release in 2015. The British songstress has kept firmly out of the spotlight while working on the album, but collaborator Ryan Tedder has been giving us brief teasers with the latest update being: "I know that with the amount of insanely good songs she has to pick from - 'cause I've heard most of 'em - this album's gonna be crazy." Oh, and it's expected to be titled 25.

5. Little Mix: TBC



After 2013's extremely good album Salute, we are more than intrigued to see where X Factor's biggest girl group Little Mix go next. Their lead singles are always slightly left-of-centre and considering we know they've been in the studio with the likes of MNEK, Becky Hill and Jess Glynne, our anticipation couldn't be more palpable.

6. Wolf Alice: TBC



When we spoke to them earlier this year, Wolf Alice described their vast influences from pop to grunge, even jesting about a Simpsons-themed EP. The band have since been tying together their diverse influences and are in the studio working on their debut album. A collection of new tracks debuted during their recent tour, old live favourites and two EPs worth of songs are all in the running for Wolf Alice's first full-length release.

7. Coldplay: A Head Full of Dreams



The band's seventh album could be somewhat of a bittersweet moment for fans. While they'll no doubt be relishing in new music from Coldplay that they'll be able to "shuffle your feet" to after the sombre Ghost Stories, Chris Martin has also alluded that it could be their final record.

8. Years & Years: TBC



We predict big big things for this British trio in 2015, and judging from their impeccable string of tracks so far (including 'Real', 'Take Shelter' and 'Desire'), we have high expectations for their debut album. Years & Years have been surprising us all through 2014 by slightly shifting their sound between alt-pop, light house and nu-soul, so to say we're eager to hear what other styles they have to come yet is an understatement.

9. Giorgio Moroder: 74 Is the New 24



As well as being his first new album in 17 years, Britney Spears, Sia, Charli XCX, Kylie Minogue and Foxes have collaborated with the grandfather of electronic music, Giorgio Moroder, for 74 Is the New 24. Need we say more?

10. Fleetwood Mac: TBC



At the start of the year Mick Fleetwood announced Christine McVie's return to Fleetwood Mac after 16 years, as well as a world tour and a new album. As of May, Stevie Nicks hadn't been able to make it to the studio due to other commitments, however McVie revealed that the band's eighteenth album was well underway. "Knowing me, I'm going to be pushing for a double album," she said, adding that eight tracks were "75% done".

11. The Maccabees: TBC



The Maccabees originally planned for their fourth album to be released in early 2014, before admitting they were struggling to 'set the mood' for the new LP.

In September the band announced that the follow-up to Given To The Wild was "nearing completion", while confirming a headline show and opening for Kasabian during their run of London gigs. Our reviewer described The Maccabees' new material as "darker [and] more forceful, but with that inimitably heartfelt touch."

12. Noel Gallagher's High Flying Birds: Chasing Yesterday



It may be the 20th anniversary of Oasis's defining album (What's the Story) Morning Glory? in 2015, but come March 2, all eyes (and ears) will be firmly on the release of Noel Gallagher's second studio album. His first outing was a post-Oasis triumph and saw him sell out arenas, but Chasing Yesterday marks the first time he has written and produced a whole album by himself. "I had all these people looking at me and saying, 'Right, what are we doing today?'" he said of the process. "I was making the whole thing up as I went along."

13. Marina and the Diamonds: Froot



Marina and the Diamonds announced news of her first new album in three years back in October. Froot has been produced by David Kosten (Everything Everything, Bat For Lashes) and is slated for release on April 6. The LP's title track, as well as new song 'Happy', have already been unveiled, with Marina Diamandis saying of the album: "This is the start of a new musical and visual era for me."

14. Mark Ronson: Uptown Special



"I always find myself coming back to that music I would play out in hip-hop clubs in New York in the late '90s/early 2000s," Ronson said of the inspiration behind his impending fourth album Uptown Special. A release date of January 26 means we don't have too long to wait until we get to hear the full release, which is set to feature the likes of Stevie Wonder, Bruno Mars (who gave Mark his first UK chart-topper with lead single 'Uptown Funk') and Tame Impala's Kevin Parker.

15. Muse: TBC



Muse have promised that album number 7 will see them "veer back towards just musicianship" and away from the experimentalism of their last album. The band are working with Robert 'Mutt' Lange (AC/DC, Def Leppard, Maroon 5) and have referenced "deep ecology, the empathy gap and World War 3" as inspiration. "It's probably going to be a bit of a rawer album and a bit more rock," Matt Bellamy has said of the LP, which is due for release in the summer.

16. The Libertines: TBC



For their first album in over a decade, The Libertines have penned a deal with major label Virgin EMI. Carl Barat has stressed that new material has "always been the plan", however the band have also expressed their desire to unearth a trove of lost Libertines tracks. With writing sessions in locations from Germany to Thailand, could we be expecting a more internationally influenced album, or will Pete Doherty and his bandmates continue to fly the flag of Albion?

17. Florence + the Machine: TBC



We know very little about Florence + the Machine's third studio album, but with a number of festival appearances recently confirmed, we can only presume we'll be hearing it in 2015. We do know that Florence Welch started working on the project in June earlier this year, saying at the time: "I am actually really excited. I sort of forgot how much of yourself you have to give to a record and how the beginning process of it is so hard. So when actually you've come through that process a bit and you can kind of see a clearer picture, you're like, 'Oh now I get it'. It's coming through to that other side now, and it feels good."

18. Rihanna: TBC



In 2014, the unthinkable happened: Rihanna didn't release an album for the second year running. There has been plenty of so-called inside information floating around, but truth is, none of us have a clue what to expect next and when we'll get to hear it. It has pushed the anticipation up to fever pitch. Will Rihanna come back with a massive pop anthem, or will she continue with the more spiky R&B we had on Unapologetic? Hopefully 2015 is the year we will all find out.

19. Britney Spears: TBC



With the chart disaster that was Britney Jean hanging over her, we're hopeful Britney Spears can bounce back stronger than ever with album number nine. Iggy Azalea - who features on the US star's upcoming new single - has already claimed it is "undeniably great", and with Spears wowing week after week in Vegas, we're praying some of that club atmosphere, showgirl sparkle and constant reminder of her incredible back catalogue of hits has influenced the songwriting process. What's more, with Britney lending her vocals to Giorgio Moroder's new album, we wouldn't be averse to the idea of the legendary producer helping out with hers.

20. Leona Lewis: TBC



The 2006 X Factor champ made a shock move earlier this year, deciding to leave Simon Cowell's Syco label at Sony and sign up with rival Universal imprint Island. However, judging by the short snippet of a new song Leona shared with fans earlier this month, it's a decision that could see her thrust firmly back into the international spotlight. "I've got fire under my feet," she felts over some suspiciously Ryan Tedder-esque stomps and a pounding piano. She is clearly warmed up and ready to go - and quite frankly, we can't wait.
