The API lets developers access its users’ music tracks, which is a powerful thing because Imeem lets users run complete tracks for free (it got rights to do this from labels, after Imeem said it wanted to try an ad-based model). Developers can also access any videos and photos on imeem, access the social graph of users, modify the metadata for the content and customize the imeem video player.
