A Great (free) Subway Pastime (that does not include reading)

I have recently discovered something almost everyone else is aware of. No, not Chai Tea...podcasts, baby. My favorite (ok, only) podcast source is the ever-friendly NPR.org. They have over 604 podcasts available including shows such as Fresh Air, Car Talk, Talk of the Nation, This American Life, and all the other "good" shows (a.k.a. ones I actually liked to listen to as a child on family road trips). My favorite? All Songs Considered - a great way to learn about new artists and old favorites, and Bob Boylan's voice is like a soothing melody. The best part is you can sign up for a free "subscription" for most shows and they just update your iTunes, Yahoo or Zune playlist with each new show. If you don't have an MP3 player, listen to the shows online.
