1. Bloc Party, "Mercury"
"My Mercury's in retrograde," sings Kele Okereke on BP's excellent first single from their upcoming third album. Apparently it's about an astrological condition that signifies "difficulties in communication," which may explain why none of other lyrics make any sense either. [Stereogum]

2. Max Vernon, "I Kissed a Girl" (Katy Perry Cover)
Max Vernon keeps the original gender pronouns on this doo-wop cover of Katy Perry's jam of the summer. We wonder if he's going to teach your girlfriend how to dance with you while he's at it. [The Music Slut]

3. RAC feat. Karl Kling, "Take on Me" (a-ha Cover)
This awesome cover is about as close as you'll get to hearing the Postal Service do a-ha's singular classic. [Hits in the Car]

4. Sally Shapiro, "Find My Ghost (Dntel Remix)"
Meanwhile, here's a wonderfully cold and lonely track from the recently released second volume of Sally Shapiro remixes, served up by Dntel, the beats-and-glitches half of Postal Service. [ Pasta Primavera]

5. The Kooks, "Violet Hill (Coldplay Cover)"
Doing their part to combat CSD (Coldplay Shame Disorder), the Kooks do a cover of Coldplay's recent hit that even a hater could love. [ Deaf Indie Elephants]
