1. Duffy, "Mercy" (live on Regis and Kelly) Regis welcomes "America's newest sensation … all the way from Wales!" In fairness to Mr. Philbin, though, she did steal all her moves from Motown. [Music Slut]

2. Weezer, "Heart Songs"
From Weezer's recently leaked, not-very-good new album, here's very possibly the worst song Rivers Cuomo's written since all the ones on Make Believe. [Idolator]

3. Alphabeat, "Digital Love" (Daft Punk cover)
The affable Danes cover DP's fifth-best song with an acoustic guitar and a tambourine (synthesizers are expensive). [Stereogum]

4. Wolf Parade, "Language City"
From their much-anticipated new album (which already leaked! It's awesome!), here's our favorite track. [MySpace via Stereogum]

5. Bone Thugs-N-Harmony, "Young Thugs"
This new song isn't bad, even if, fifteen years later, that fast rap-singing that these guys do doesn't really sound any less annoying. [Nah Right]
