IMPORTANT: You must set up 1 repeating command block in order for the addon to work - function music start

first, you must make two things - a cassette and the player

CASETTES:

First make an empty cassette

it's made with 6 black terracottas, 2 blocks of glass and an iron ingot

The cassette texture is not final and will be changed in the future updates

Now you add music on it. Right now you do this by crafting a cassette and a music disc together, but this WILL be changed in the future. Also, right now there's only one cassette, Chirp by C418.  More will be added soon

MUSIC PLAYER:

2 blue concrete, 2 light grey concrete, 1 acacia button, 1 stone button, 1 redstone, 1 diamond block and 1 jukebox

HOW TO USE THEM:

First insert the cassette into the player:

 Now you have the player with a cassette

To turn it on throw it out of your inventory. The player will turn into a playing player and the music will start to play

to stop the music you throw it out again

to eject the cassette you must stop the music (here's what happens if you don't do that:

) and put it in the crafting grid

You'll get this item:

Throw it out of your inventory and you'll get the player and the cassette back

MORE UPDATES AND MUSIC SOON!

Update 0.4.0 Alpha

• Added 4 new discs! 2 from vanilla Minecraft (Strad and Wait) aaand 2 from the legendary Minecraft villager band - The Noteblocks! We've partnered with them to bring 2 of their songs to the cassettes - Sun and Zombies

What's great is that they don't replace any existing music! Only cassettes are included with this addon tho. If you want the discs from the picture, you should download The Noteblocks' music

Because there are no Sun and Zombies discs in vanilla Minecraft, those cassettes have a different way of crafting:

Update 1.0 

• 4 new discs added - 11, 13, Pigstep and otherside. Thus, all of the vanilla minecraft music discs are added to this addon - hence the 1.0 full release:D

If you'd like your music to be included in this addon, contact me on Twitter
