Utilize ComputerCraft Music Player

wave-amp - A fully featured music player - ComputerCraft | Programmable Computers for Minecraft

A very interesting project, I would suggest you use it on the server for background music.

EDIT: nvm no use

 

it looks preety cool the question for me is can it play youtube?

 

I do not know. I could add that functionality if it's open source.

 

It can play only songs that have been converted to work with Minecraft's note blocks, so unless you plan to write a script to convert youtube streams to a noteblock format, you probably couldn't add that functionality.

 

nvm, discarding post.
