A Track A Day on Ping
If you use iTunes and have updated to the version 10, you have access to their new feature, called Ping. It's basically like Facebook or Twitter, except in the iTunes store. It's a place to share your thoughts on the music you like and see what other people have to say about their music.
Part of my daily routine is listening to music while warming up on the guitar. I'll casually play along with a few songs to get some creativity flowing, and then begin my practice routine. I've started posting one of these tracks to my Ping profile each day. If you're curious what I'm listening to, this is just one more place to find out.
