A sort of sound recording device.

I think it would be a pretty cool idea to have a sort of recording device in minecraft where you could make a blank disc and then use some kind of block or item that can record the surrounding stuff around you and then you can replay it. maybe make it so its minecraft accessible even and that jukeboxes can now also be put into minecarts. it would be pretty funny seeing a warden chase around a jukebox in a minecart. not to mention people who enjoy making note block music could record their songs and replay them whenever they want without having to worry running along their huge contraption just to listen to it.
