The times they are a-changin'. Napsterbashing iTunes-eschewers Metallica are now available for single track downloads at the iTunes Music Store. Considering that only a short time ago they wouldn't go near the service with a 10-foot drumstick, this is pretty big news.
Ironically, the band is available on Napster as well.
Someone call Neil Aspinall and tell him it's time to capitulate.
