MidiRadio attempts to imitate songs in game by sending tuned in players note block sounds. MidiRadio is inspired by and expands on the original works of Protected in their plugin MidiBanks, now managed by jfmherokiller.
Rather than play note sounds through note blocks however, MidiRadio streams the players individually note sounds when they are tuned in to the radio, regardless of where they are at.
MidiRadio is very easy to setup in its current stage. Just stick some midi files into the plugin's data folder and it will start playing next time the server starts up. By default players are not tuned in to the radio - however typing /tune in will quickly have them listening to the waves in no time. You can opt out too by using /tune out.
Players with the midiradio.play permission can use /play to change the song too!
