Seems to be a particularly strong selection at the moment from Emusic, possibly as the majors shrink and more and more artists make the kind of recording deals they can pick up. I have on my to-download list new albums from:
Pet Shop Boys
Explosions In The Sky
And recent downloads have included:
School of Seven Bells
Cavern of Anti Matter
Not sure what the long-term business model for mp3s is, it’s telling they have recently introduced their own streaming/playlists app. But all power to their elbow while they can keep going.
