A stretch feature request: integrating with music functionality

[64bitpandas]

We are often indecisive about what music to play during studying, so this feature set will mitigate that and provide an additional layer of functionality that would be nice to have (but not too important):

• Save a playlist of songs to a file (from youtube)
• Commands to add/remove songs from the file
• During work time, !music will play random songs until the time is up
• If !play is invoked, it will override the shuffling to play the specified song
