I usually listen to Pandora on my cell phone while I'm working out, and I usually love it. I have a Lady Gaga station that plays Katy Perry and Kesha and a bunch of other female pop singers... The downside is that I don't really have much control over the songs beyond skipping, so I'm trying to make a playlist.
So what kind of music do you listen to while you work out? Who's in your playlist?
