Use Spotify with Team Groove

[stiffneckjim]

For Team Groove to be able to independently drive a play list it needs access to music. This means it either needs to be integrated with at least one music streaming service or have access to music files some other way. The plan is to start with Spotify because it has a convenient Web API, an extensive catalogue and a free tier for membership.

The steps to integrating with Spotify include:

1. Authenticate Team Groove with Spotify - this is authenticating the application itself but will require an active account on Spotify that will need to linked by the person setting up Team Groove
2. Populate a play list with a play list from Spotify
3. Add tracks by searching Spotify and adding them to Team Groove play list
4. Play tracks in Spotify according to the votes they have received from Team Groove

Assumptions

Team Groove will store play lists locally but these can be populated from Spotify.
There is no synchronisation between Team Groove and Spotify.
When a play list is pushed from Spotify to Team Groove, Team Groove will check all the tracks in the play list are valid, including discarding duplicate tracks.
