I have been using Spotify for a while now, and generally think it's a great idea, and provides a great service. I was considering subscribing for the access to their mobile service, though one factor recently put me off.<p>I don't know how widespread this is within their library, but Spotify interests me in the niche music they serve. When I first got the beta, I loved that I could find a few of the more obscure albums of Irish music on there (don't laugh!) However, a few weeks ago, a large selection of these disappeared. I signed in one day, and many of my playlists were next to empty.<p>I presume that they encountered a rights issue which forced them to withdraw the music. But from an end users point of view, my quality of service was diminished, without prior warning.<p>Shame really, but the experience was enough to put me off subscribing.
