Apologies if the SKD already supports this kind of usage.
There are a few great games out there that analyse music and use it as in-game levels - games like Audiosurf and Beat Hazard.
The problem with these games: If you use Spotify, you can't use a lot of your music in them.
If Spotify were able to create an SDK (perhaps linked with the cache on your computer) that would enable games to use it like this (they would need to be able to analyse the whole track.
I know that the developer of Audiosurf Air (http://air.audio-surf.com/) wants to work this in the game, but his latest tweet about it (a few months ago) says that he isn't able to contact Spofity.
I think that working out a way for games to use Spotify would be a huge plus for both the games and Spotify itself.
