After releasing seven studio albums, the Eagles are the biggest selling American band of all time (more than 150 million albums sold worldwide), have won six Grammy Awards and had five singles reach No. 1 on the Billboard Charts. But they also have plenty of underrated gems in the catalogue that are just as good, or even better, than the hits. Here are five of the Eagles most underrated tracks:

Ol' 55 from On the Border (1974)

Never released as a single, "Ol' 55" is a standout track featuring those amazing harmonies the Eagles are famous for. It was written by Tom Waits for his debut record Closing Time and the Eagles do a fantastic cover paced by Glenn Frey's lead vocal as he sings of leaving a lover, driving away early in the morning. The trademark Eagles harmonies for the chorus will give you goosebumps when they sing "And now the sun's coming up. I'm riding with Lady Luck. Freeways, cars and trucks." Interestingly, Waits said the Eagles version was too "antiseptic".

Try and Love Again from Hotel California (1976)

Because we love Randy Meisner's voice so much, "Try and Love Again" gets on the list. And it's a fantastic song, to boot. The Eagles lost a lot of their feel when Meisner left the group and was replaced by Timothy B. Schmit, but we can still go back and listen to this gem. Glenn Frey handles the lead guitar, while Joe Walsh adds the Gretsch guitar flavouring. Meisner shows his penchant for writing amazing lyrics with lines like "Right or wrong, what's done is done. It's only moments that we borrow ... But the thoughts will linger on".

I can't Tell You Why from The Long Run (1979)

While I can't Tell You Why was released as the third single from The Long Run album, the reason for its inclusion on this underrated list is Glenn Frey's phenomenal guitar solo. There has been debate about who played the solo, however, both Don Henley and Frey himself point to the latter and not Don Felder, as many believe, for the great-sounding fretwork. While a fairly generic song overall, Frey's fade-out solo brings a deeper feel to the track. It's not technically dazzling, but the notes are perfectly chosen.

Seven Bridges Road from Eagles Live(1980)

Perhaps the pinnacle song when it comes to harmonies for the Eagles. The band used to sing it as a warmup prior to hitting the stage during the Hotel California tour through a single mic for the waiting audience. Written by Steve Young, the Eagles sing it in perfect five-part harmony with a sparkling acoustic guitar accompaniment. Another song that brings goosebumps. We also love the fans screaming during the quiet parts.

Tequila Sunrise from Desperado (1973)

Penned by Glenn Frey and Don Henley, "Tequila Sunrise" has a cool Mexican flare in the guitar, with lyrics most people can relate to or have even lived through, watching the sun come up after a night of drinking. The lyrics were originally intended to refer to the popular drink, Tequila Sunrise, but Henley told Frey to take it from another angle as in the sun rising after drinking tequila all night.
