Levi's Unbuttons Fresh Musicians, Fringe Celebs

"Everyone has something to reveal. They just need to be unbuttoned," Levi's croons, crowning its "Unbuttoned" campaign for the classic 501 jeans with "spoonfuls of soul and swagger" (I just love that line). On personal subsites, three artists -- Estelle, Nikka Costa and Wale -- describe why they became musicians and pass on a free track for users to download.

Each MP3 has a different sound, but they all feel big and breezy. (Slightly off-topic, isn't it nice to see so many companies share downloadable ear candy? It's like trick-or-treating, except with iTunes instead of a pillowcase.)

Music isn't all Levi's is baring. Other celebs with something to share include the adorable Jamie Bestwick, who's giving away a free BMX video, and there's a Perez Hilton giveaway coming in September. (They gave us the link, but it's still doorknob-dead.) What Perez is giving away I'm sure I don't know, considering his two cents always come free.
