When I was farming music disks/discs on our server, I got a ton of similar disks! So I asked myself if it wouldn't be nice if we could have a new villager (I assume it would be named musician or something like that) who would trade music disks, jukeboxes and noteblocks. One of my friends is already working on a mod for it, but I thought it would be also cool if it is in the "vanilla" version of the game (I don't think that it is planned by now). I hope Mojang will implement this into the game and would love your thoughts about a new type of villager!
