Have your heard Rihanna yet? She of "Umbrella" fame, her hit collab with Jay-Z that's been all over the charts, radio, and Web lately. You can stream it for free on Download Music--and this week she's also the star of our ongoing Best New Music video report, a collaboration with our buddies over at CNET TV. Watch and listen as Anngie Dehoyos gives the lowdown on what makes the song so gosh-darn great. Then catch Peter Gavin's take on indie heroes Blonde Redhead and my own shakedown on the haunting new album from Charlotte Gainsbourg, daughter of French icon Serge and a well-known film actress to boot (think Science of Sleep).
