Ok, to report back, I picked up:

Interpol ~ Turn On the Bright Lights
Sparta ~ Wiretap Scars
Rilo Kiley ~ The Execution of All Things
Doves ~ Last Broadcast

Overall, I have enjoyed the Doves and Interpol. Sparta is still the active playlist, and seems to be more rockish then the other two. Still deciding what I think about it, but so far it's pretty good. Rilo, not really an entire album I enjoyed. The last parts on a few of the songs were weird, and didn't seem to really fit.

Thanks for the suggestions everyone. I'll keep the others for a later time, as I am mostly happy by the 4 CDs that I picked from the list.
