1. SummerMash ’13 – DJ Earworm

How do you indie-fy the mainstream? Mush it all together into a way the masses haven’t heard it. Jordan Roseman has been making a name for himself as DJ Earworm since the early 2000s when he started taking the year’s top 25 hits and combining them into some darn catchy tunes. This summer’s collaboration includes songs such as “Blurred Lines”, “Heart Attack”, “I Love It” and “Can’t Hold Us”. You may dislike the individual songs, but together it’s an earworm, indeed.

2. Psychosocial Baby – Slipknot vs. Justin Bieber

If there was ever a song to make Beliebers and goth teens agree that something was sacrilegious, it would probably be this. YouTube artist Isosine rose to fame with this pop-screamo jam in 2011, and it remains just as fun to listen to today. Hands down, this is my go-to song when people ask what the strangest thing in my music library is (because I know they wouldn’t be able to handle the really obscure stuff, and this song is guaranteed to make their jaws drop).

3. Million Dollar Gold Digger – Lana Del Rey vs. Kanye West

Oh Kanye West. Just when we thought we couldn’t love/hate you even more. He and self-proclaimed Hollywood sadcore princess Lana Del Ray work surprisingly well together, both with their skewed and somewhat terrifying views of relationships. With its bouncy beat and sensual lyrics, the song just makes you want to twerk – or something.

4. Midnight-Galactic – M83 vs. The Beastie Boys

Can a song be considered sci-fi? Yup. The in-your-face raps of the Beastie Boys meet the electronic vibes of M83 on 2012’s Midnight-Galactic, and the result is out of this world. Synthpop and screaming never sounded so good, so I dare you to not start bopping around and moshing to this one.

5. Radioactive Swimming Pools – Kendrick Lamar vs. Imagine Dragons

There’s just something about rap and alternative working together in perfect harmony. Isosine makes the list again with a combination of Kendrick Lamar’s haunting vocals and the equally chilling tune of “Radioactive”. The juxtaposition of abrasive victory and pessimism easily make this one of the best mashups I’ve heard in a while, and I have 100+ plays of this recorded in iTunes in under a week to prove it.

6. Boulevard of Broken Songs – Party Ben

What do high school aged emo kids grow up to be? Hipsters. Might as well give them a throwback to the good old dramatic days with some Green Day. This collaboration hooks Billie Joe Armstrong and gang up with the likes of Oasis, Travis and Eminem in one of the first and most popular internet mashups. This will definitely take you back to a time of too much eyeliner and LiveJournal, but who says that’s a bad thing?

7. The Day the Music Died – Mashup Germany

Fourteen artists and musicians across all spectrums of music, past and present, come together to honor the day the music died. Put those lighters in the air and sway to the mellow beat throughout in what can only be called a true tribute. Maybe some of the artists like Elvis and Mozart would roll over in their graves to be grouped with the likes of Jessie J and Kelly Clarkson, but alas, the smooth result is incredible all the same.
