The killer app of Spotify has been expanding my horizons past the 30 tracks on my MP3 player. But that seems to have stalled. I do like being notified when bands I like release new music. I am hopeless at keeping up with music so thats useful.
One of my main complaints with Spotify is how lousy it is with that for me. Release Radar is usually a pile of songs almost, but not quite, entirely unlike what I listen to. Bands it knows I follow since it makes playlists for them will have new tracks never show up unless I go to their page or it comes up randomly.
I have no idea what the "follow" feature does because it doesn't notify me for new music from followed artists, and "What's New" doesn't include new releases from all of them. But it has given me four notifications that Journey is coming to Nashville in case I didn't get it the first time.
Release radar does seem useless.
