Many folks know that iTunes is bumped to version 4.5 now, breaking backward compatibility with network shares.
That aside, I've discovered free music on iTunes (without Pepsi deal, which I can't get in Japan, dammit!). Every Tuesday, Apple is making a track on iTunes free. For the one year anniversary, it seems there'll be a new song each day.
Yesterday was a very bad Avril Lavigne song called Take Me Away, and today is Courtney Love's Hold On To Me (three stars).
Credit Card required to get an iTunes account even though they're free tracks.
