It would be really cool just to have the whole lot available as a ZIP file, like a mini version of the HVSC!
There are about 400 songs from CPC demos in AYGOR (

and just a few from games. In the most of the demo music the playing time is undefined yet and no credits to the authors.
It will be always downloadable as one .zip file
All of the music is in the .ay format.
It is planned to develop this format to support even more than ZX & CPC music.
This format, with some minor updates, may support more machines with Z80+AY/YM onboard.
The hardware requirements (Z80, AY and interrupt frequency, output ports) will be defined in the file header.
That's why code rips (player routine + music data) are needed to play samples and other non-interrupt based sounds.
