How to copy: click three dots → click view deck source → click any music → click copy → done!

I also forgot to mention another thing, the music will only work if you tap it. So if you want it to play by itself, go to "logic" and change the "when this is tapped" rule to "when this is created" rule so the music can play by itself without tapping! ALSO, the music is PERMANENT. So if you want it to play it looped add a "repeat every __ seconds" rule beneath the "when this is created" rule and type the seconds you want it to be looped and it will be looped the seconds you put!

Also After Copying, go to your deck you want to put music then click the plus and finally scroll and click the music you copied!

I forgot to mention that after you click view deck source, click the first card
