I have numerous songs, and I don't listen to the all the time. I might listen to some songs today and different ones tomorrow.
I also have a iPod shuffle and that is what really got me motivated.
I have all kinds of music:
Godsmack, Hinder, Nickelback, Wicked soundtrack songs, Sweeny Todd songs, Lita Ford, Pink, Christina Agulera (spelled wrong), Motley Crue, My Chemical Romance, dance club music, Kid Rock, 90's music, just all kinds.
