A big surprise is an announcement today that Bigpond Music (A Telstra owned service) has from today started offering tracks in MP3 format. This is a move away from the DRM windows media format that all their songs were sold as.
When Bigpond started offering music sales a few years ago I was an early adopter and purchased music from their offerings. However it soon became obvious that the windows media DRM was a difficult beast to deal with.
