hmm, depends on the weather and where I'm driving, and what time..

Newsboys! Any one of their 13 CD's are perfect for me!

(Albeit I prefer their newer stuff....)
upbeat songs include in no particluar order:
Sweet home alabama- Lynyrd Skynyrd
Audio Adrenaline- Can't take God away, CHEVETTE! (it's awesome for driving), mighty good leader,
Christine glass- Crazy all around
Most of the above songs are only played when I'm cruising on the backroads, isntead of sitting in traffic.
I'll usually listen to talk radio for the first 30 minutes to school until I get out of the city and traffic, then I can roll down the window, turn up the music and cruze!
