> it just lists all of the songs that I have saved from an artist, ignoring the album information
AM definitely has Spotify beat here. Click an artist, see their albums, choose an album to listen to. All in one view. It seems so natural ... I wonder if this is because I learned to curate my music on iTunes, and it is just a habit?
But for music discovery, open development practices (this is the biggest reason I switched from AM to Spotify - knowing that no matter what kind of thing I want to hack together, Raspberry Pi connected to BT speaker connected to projector, I would be able connect Spotify to it somehow), and social music experience, I think Spotify has AM beat.
