I love podcasts. I listen during naptime and while working out. I subscribe to about 30 but there are a handful I really look forward to getting:

Agatha Christie Radio Mysteries-The original episodes from oldtime radio
Cast-On-My favorite knitting podcast. Her show is like reading a knitting magazine.
Librivox-Free audiobooks in the public domain read by volunteers.
Wait Wait Don't Tell Me: NPR's News Quiz, the only news I get during the week
Wormwood: A cross between Twin Peaks, X-Files and every other twisted story you love but are afraid to admit.
Yogadownload.com-free 20 minute yoga classes. Pictures provided.

Like I said, I listen to many, but these are the one's that I reserve for special moments.

And I'm thinking about blogging a "Favorite Thing Friday." Time will tell.
