Getting Play to work:

- Change Gemfile.lock's version of mocha to be 0.11.1
- Open iTunes -> select iTunes DJ -> Start playing a song

Some caveats:

- iTunes Match songs (that are not on disk) won't queue
- Frontend seems sluggish, but it could be the machine it's on (not super powerful, but should be able to keep up)
