Weezer [ tickets ] has digitally released six Christmas songs that originally were featured on the iPhone application "Tap Tap Revenge Christmas With Weezer."

The music was recorded specifically for the iPhone app, but demand from non-iPhone users was so great that the band decided to make the songs available at digital retailers, including Apple's iTunes store and Amazon.com, according to a press release.

The digital EP features Weezer's interpretations of six classic holiday songs--"We Wish You A Merry Christmas," "Silent Night," "O Holy Night," "The First Noel," "Hark! The Herald Angels Sing" and "O Come, All Yet Faithful"--which are the first songs ever specifically recorded for an iPhone app.

Weezer also contributed a song, "Troublemaker," to Warren Miller's latest ski film, "Children of Winter." The film also is featured in the video for the band's latest single, "The Greatest Man That Ever Lived."
