Spotify Mighty

Just heard about this:

Anyone familiar with it? Should I be hopeful that maybe one day something similar will be created for Napster? Or, even better, that I might be able some time soon to use my beloved Sansa Clip to again listen to subscription music services?

Seems like Spotify recognizes that not everyone wants to have to use their phones to listen to music.

Not sure what this actually does, especially since you still need your phone to operate.
