This mod adds a single simple block: the disc shelf. Crafted by using a note block above a chiseled bookshelf, it lets you store up to six music discs in the shelf's gui inventory. It responds to redstone pulses by ejecting a disc at random. Right click with a disc in hand to add it quickly to the shelf's inventory. Now supports Etched mod music discs.
Disclosure: Some of the mod was created using ai to speed up workflow mainly for reduced time spent typing things out line-by-line repeatedly when making minor adjustments.
