I think theres a good opportunity here for people considering getting into the streaming space. For example, SoundCloud and Youtube allow you to access streams without tying yourself in with DRM. Artists want to be heard and fans want to be able to access that content easily. With services out there being really good for publishing music, a streaming service that allows an artist to directly engage their fans would be really interesting.
The challenge is creating a community for both the musicians and fans to interact meaningfully. Musicians want to be free from being lumped in with the noise and fans want to be explore that content freely. I think for most streaming services out there, this hasn't really been totally figured out, although Spotify and SoundCloud are trying to.
