Downloaded Spotify on my work machine ages ago, but only just got to installing it on my mac at home. This works extremely well with the Bowie/Berlin query set, which I can't show because you have to log in, but it has all the tracks, and its really quite an impressive service. Searches on the set provide not just the album, but also extra tracks e.g. covers. Only problem is that my version of little snitch keeps popping up with messages, and if you don't accept the connection, the track won't play! An independent review of the service is provided by David Toube.
