Lovelies, I need your help AMPing up my iPod for working out. I lots of songs on my iPod, but a lot of them get old quickly. Help!

I’ve recently gotten really into running. I got some new running shoes and some great workout clothes. However, I cannot run without my iPod. And although I’ve been making do with the songs I have, I’m getting sick of listening to the same 4 or 5 songs over and over again. I need some new suggestions, old or new music, to help jazz up my workout playlist!

What are some of your favorite songs to work out to?
