I think I have got a new idea that would work great with Blockland. The server host should be able to stream music/sounds to all the players across the server and maybe other players could stream to players playing their mini-game, rather than have it play through a music block (as music blocks have many limitations). I'm not saying that this system has to replace the music block, but I think it would work very well. This allows for the music-file size limit to be removed (or set through server settings), allows for stereo play, and would work great for events, mini-games, etc.
What do you guys think?
