Trying to make airpods

Hello !

I'm trying to make airpods mod in Minecraft with MCreator. This is just a fun project for a friend's server.

How does it works:
- The player crafts Airpods
- The player should have a music disc on him
- The player should type /airpods
- The mod plays the music disc the player has on him

Problems:
- Everybody hear the music (well it is not a such big problem, but I first wanted it to play only for the player
- The music doesn't follow the player, it stays where the music started, and I want it to be played on the player everytime when he moves, the music should follow him.

Any help is welcome ^-^
Thanks
