Hey Turbofan, if you have an Ipod, go to Itunes.
In ITunes, in the upper left there's a small window for Itunes Store. Click on Music, then click on Nike Sport Music. You'll find quite a few playlists in there to workout from. It really depends on your genre of music you like.
Also you can google the same thing.

I've done the same with some pretty good results.
