Last.fm does this and has existed since the early 2000s. It had such a nice, active community in the audioscrobbler days. The community is a ghost of its former self after the sell-out to CBS, departure of the founders, redesigns that were reviled by the community, and advent of spotify, which slowly implemented many of the features that made last.fm useful.
