"Electrical" Instruments

Not an electric harp, but a harp that runs on electricity. The reason for this suggestion was an idea with the new speaker tiles and the fact that music in this game on the instruments can be very beautiful. I think this means that a great idea for the game would be an electric instrument for automation that when linked with a chart will play the song in a radius around the instrument. This, combined with other instruments, would allow single players to have access to the great music from the instruments, and also have themed music for parts of their base.

Electric instruments would also be cool, as would the ability to create your own score sheets to play in the holders when synced to other players.
