This is actually pretty close in functionality to the beloved Spotify client on my old 5800XM, which I was sceptical there'd ever be a decent N900 equivalent of.
Click on the album and it plays the whole album, with cover art.
Click the artist and you get a biography.
Works well in background, with a very occasional skip.
Just needs sorting of the columns and playlists (+offline?), now.

The guy behind this needs to come forward and take a bow.
