The idea currently on row 17 "apt-get update/upgrade for music" is very good IMO. I would use this service.<p>You could also expand it in various ways beyond tracking new releases for a single band to make it more of a music discovery service, e.g., (a) tracking side projects started by members of a given band or band "communities" where there are several inter-related artists and bands that appear in various ways in one another's work (like Broken Social Scene, Wu Tang Clan or The Bird and the Bee) (b) tracking other bands/albums/songs etc. that someone had a hand in (e.g., show me new releases that Pharrell Williams produced) and somewhat obviously (c) tracking new releases in a given genre, which could be very fine grained.
