What's up with the versions? My Tiger install reports iTunes 4.7.1 (30). I found 9.2.1 on the Apple website. Why doesn't iTunes update automatically when I do a software check through the system? What about all the other versions in between? What's the consensus here as to which one works best for PowerPC (remembering I'm on a G3 with a 600MHz CPU please). I just need a slim/powerful player that doesn't do anything fancy. iTunes Store is off the table for PowerPC architecture anyhow, right?
