'Glee' Stars Talk Soundtrack, Christmas Single, Solo Careers

A Volume 2 is also expected in December.

Fox's new Wednesday night juggernaut "Glee" has not only made a huge impact on the television landscape but is also turning the music world on its ear. Every Thursday morning, the songs from the previous night's episode are posted to iTunes and immediately fly up the singles chart. This week, the show's first compilation, Glee: The Music, Volume 1, debuted in the top 10 on the Billboard albums chart.

The compilation features fan favorites like "Don't Stop Believin' " and "Bust Your Windows," but the cast all agree that one tune in particular is the highlight.

" 'Somebody to Love' is my favorite," castmember Lea Michele (who plays Rachel on the show) told MTV News.

"I would say the same thing," added Cory Monteith (Finn). "I have no original thoughts of my own."

"I'm a huge Queen fan," Michele said. "I think Freddie Mercury is one of the greatest performers of all time. So singing it was awesome, and I think as a group it was the first time we felt really good together. We really became a unit."

Michele and Monteith both love the soundtrack album because it shows just how diverse and talented the cast of "Glee" really is. "No matter how good a singer you are, it's tough doing all these different genres at once," she explains. "So one week you're doing Rihanna and the next week you're doing Celine Dion."

Considering the success of the show and of the first soundtrack, it's no surprise that Volume 2 is already set for release on December 8. That compilation will feature "Glee" versions of the Pretenders' "I'll Stand by You," John Lennon's "Imagine" and the Rolling Stones' "You Can't Always Get What You Want."

Also in the works is a special Christmas single that the cast is recording this week. "They told me what song we were doing, but I honestly forgot," admits Amber Riley (Mercedes). "But it's a traditional Christmas song."

Riley added that this only represents the beginning of recorded output by the "Glee" cast. Matthew Morrison has a solo album in the works and the rest of the cast will get their shots as well. "We met with the head of Columbia Records, and he told us, 'All you guys are so talented, and you're all going to put out albums and be huge,' " Riley said. When she gets the opportunity, she will already have her wish list of collaborators in mind. "I would reach out to Jazmine Sullivan and to RedOne. And you know what? I would love if John Mayer would write me a song. I am one of his biggest fans. Continuum is, like, the album of my life."
