I know most people usually run with high-tempo dance music, but I prefer to run with midtempo alternative songs - Arcade Fire, The Shins, even Lana Del Rey sometimes. For me, the music that sounds best while driving is the best for running.
As for headphones, I need to get a new pair for running

my old ones broke, so now I have a pair that's way too short, so I have to hold my ipod in my hand while running
