btrfs can compress files in-place, making for a really shitty workaround

I suppose I could even run an rsync to get the list of modified files which would be copied, and then use that list to be specific about which files btrfs should examine and compress.  But.  That's just silly.
It can now play a simple collection of notes.  I could implement a text file inputted chiptune format, but I'm not that crazy.
