In addition to the covers the group has performed on the series, including Destiny's Child's "Bills, Bills, Bills," Train's "Hey, Soul Sister" and Pink's "Raise Your Glass," the album will feature two previously unreleased tracks – the group's performance of Barbra Streisand's "What Kind of Fool," which opened the 2011 MusicCares Person of the Year gala honoring Streisand, and a never-before-released rendition of Rod Stewart's "Do Ya Think I'm Sexy?"

Criss and the Warblers made their series debut with a rendition of Katy Perry's "Teenage Dream" that became the best-selling single the series has released to date. Criss, who plays gay Dalton student Blaine on the show, was previously best known for a college "Harry Potter" musical parody that became a YouTube hit. The Warblers are voiced by the Beelzebubs, a real-life a capella group at Tufts University.

"Teenage Dream"
"Hey Soul Sister"
