I listen to a lot of podcasts lately. My music selection is feeling a bit overused since I've been running a lot this year and have only bought new music once or twice.
Podcasts:
The DIS
The History Chicks (history geek here)
How Did This Get Made? (makes fun of bad movies)
Coffee Break French (multi-tasking! Learn a language while you run)
Another Mother Runner
Music:
I recently downloaded the soundtrack to the Broadway show "Rock of Ages". Lots of good 80s running tunes in there: We're Not Gonna Take It, We Built this City, etc.
There are a number of first and second season Glee songs on my list: Raise Your Glass, My Life Would Suck Without You, You Can't Always Get What You Want.
I am totally a music person in life (singer, studied music in college), but I have a hard time finding new music that I like running to.
