As a high school student commuting each day on the R and 4 trains my Walkman didn’t get much of an underground radio signal. Back then I lugged around cassettes, then CDs, MiniDiscs for about six months, and finally mp3s on my MP Trip. My transportation hasn’t changed much, I’m still commuting underground, but now I’m spending the time listening to podcasts.
Instead of sharing my full subscription list here are a few that I’m into right now. The only way I’m able to stay current is to listen at double speed. Try it sometime. You might like it too.
