Placebo [ tickets ] will unveil its video for the single "Running Up That Hill" next month, the group announced today (4/26) via a press release. In recent weeks, the band had asked fans to submit video footage of themselves singing the song; the finished video will be composed entirely from those submissions.

All of the original fan-submitted footage will be available at the band's Motionbox page, and the finished video will debut May 16 on both the Motionbox page and the group's MySpace page.

Former "American Idol" contestant Carrie Underwood [ tickets ]'s "Idol Gives Back" music-video package, which was filmed during her trip to Africa earlier this month and aired on last night's (4/25) "American Idol" charity special, is now available for download exclusively via Apple's iTunes Music Store. Proceeds from the clip, which features Underwood's acoustic rendition of The Pretenders' "I'll Stand By You," will go to the Charity Projects Entertainment Fund (CPEF), which distributes money to other charitable organizations. More information is available at the "Idol Gives Back" website, through which users can make donations.
