ZX81 playing SID-songs!

I made a version of Zeddy Audio Jukebox that plays 8-bit audio through a simple R2R-DAC on port B of the AY/YM sound-chip. Sample rate 22109 Hz is less than 0.27% faster than 22050 Hz, so easier to convert audio with any sound programs.
Here is a binary release with a player that replays the wonderful SID-tunes Ocean loader 2 and Monty on the run.

EDIT:
Updated the binary to remove a pesky bug. And the playlist is now in BASIC, so easier to edit on a real ZX81. Updated the documentation at https://github.com/NollKollTroll/zeddy-audio-jukebox
Even more bugs squashed
Bug: 3 cycles too short in playing!
