This mod adds more tuning cylinders with music published under a free license.
It does not add these items to any trader or such, you'll have to add them manually to your game/ server or make use of them in creative mode.

The credits can be found in the "Master" mod. You'll also need to download all "Volume" files.
In the unlikely case that there should be any issues with copyright, please let me know and i'll remove the file in question.

The music included is not necessarily vanilla friendly.
