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.
WHEN DOWNLOADING THE OTYACRAFT DEPENDENCY MAKE SURE YOU ENABLE "ALPHA FILES" ON CURSEFORGE, AS AT THE MOMENT ALL 1.20.1 FILES ARE UNDER AN ALPHA RELEASE.
YOUTUBE LINKS ARE BUSTED RN (youtube API changes or something idk), THEY WILL BE FIXED IN A WEEK OR SO WHEN I HAVE TIME, IN THE MEANTIME EITHER IMPORT TRACKS FROM OTHER PROVIDERS (or download the songs from youtube and upload them yourselves), AND USE RADIO LINKS INSTEAD OF YOUTUBE LIVE LINKS (eg. the stuff from https://streamurl.link)

i just recorded a quick video showing it off here
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.
