Music recs?

BrittSwimsJDRF

I was wondering if anyone had any good music recommendations for longer workouts? I like indie, alternative, and almost anything. I'd prefer to stay away from top 40, but I've been listening to The Killers and Kings of Leon for the past 3 weeks, and am looking for something with a little more "oomph" but not too hard. Any recommendations would be great!!!! I have my first 1/2 marathon scheduled for November 14th here in San Antonio, and would like to find extra motivation through my music.

Thanks, and happy 4th to all!!!
