Here are some on my ipod. Not sure what your taste is.
I wouldn't call most of these super fast songs, but good for general aerobic running. I find I run faster to slower music, actually. Some of my best runs have been while I've played Alexi Murdoch, really mellow stuff. You might find the same if you try it.
Better Than - John Butler Trio (also check out Treat Yo Mama and Daniella; oh heck, anything by JBT is terrific)
Into the Ocean - Blue October
New Shoes - Paolo Nutini
Hamoa Beach - Gomez
Some of my "I am woman, hear me roar"

songs:
You Know I'm No Good - Amy Winehouse (bluesy; love it)
Fidelity; Better - Regina Spektor (another great CD).
Little Plastic Castles - Ani DiFranco, great kick butt song
Here's are a few truly fast songs:
The Yeah Yeah Yeah Song - Flaming Lips
No Bad News - Patty Griffin (from her wonderful new CD)
Mr. Brightside - The Killers
Suddenly I See - KT Tunstall
Soul Meets Body - Death Cab for Cutie
O Valencia - Decemberists
Anyway, just some ideas. Changing up the playlist once in a while is always a good thing.
