I just started an account with Rdio today to assemble a playlist to go with Battlefield 3. I was using playlist.com for this kind of stuff but Rdio seems far superior. Please don't misunderstand my taste in music, I don't usually jam Kanye and Linkin Park till my ears bleed, but back when Battlefield 2 came out I found that any kind of high energy music actually improved my play, so I pray the same will hold true when I fire this up in tandem with BF3 tonight.

Any suggestions? What music puts you in the zone?
