This is a pretty simple mod, the visuals in the original Iam Music Player mod didn't really fit vanilla, much less Create, so I simplified and tweaked up the models a bit as well as made the recipes use Create items.
I considered making the devices require rotational force to be powered, and maybe having the speaker/boombox be powered like the backtank but that would require reworking the library that the original mod was based off of. If there's a demand for it (or if I'm really bored down the line) I might do that for a later update.
yt works now, remember to use otyacraft engine alpha release and if that doesnt work use the otyacraft engine updated fork
