Spotify's been up for nearly two months, and it's shown amazing growth. Now it wants to find its way into everything else you do on your iPhone by handing developers and Premium users the new Spotify API.

Called libspotify 9, the code will allow the program to live inside any app developers can think of. Spotify sessions are already handled pretty well by iOS multitasking, but, as excellent as the app is, you tend to have to leave what you're doing to change playlists. By sticking the functionality into games, for instance, you won't have to jump out of what you're doing in the middle of a campaign. Pretty neat. [Spotify Blog via ReadWriteWeb]
