It's water cooler day, the day after the Grammy Awards and the time for people to talk about what they thought when Paul McCartney jumped on stage with Linkin Park and Jay-Z, or what they thought of Kanye's ego this year. U2 came away as the big winner, taking the trophy for album of the year (How to Dismantle an Atomic Bomb) and song of the year (for "Sometimes You Can't Make It on Your Own") Green Day won record of the year for "Boulevard of Broken Dreams." Mariah Carey

Kelly Clarkson became the first "American Idol" contestant to win a Grammy. She won two, actually: best pop vocal album (Breakaway) and best female pop vocal performance ("Since U Been Gone").

Mariah Carey won three awards but it was John Legend who won for best R&B album (as well as best new artist and best male R&B vocal performance).

The Grammy website has the complete list of winners. Good coverage can be found at the NY Times, MTV.com and Billboard.com.
