After some musical fun with the Commodore 64, I moved on to the Amiga 500 (all of those tunes are in the mod category). When I outgrew the Amiga, a moved on to the PC, utilising the S3M format, then XM format, followed by the IT format. The MP3s you can see there were still tracked.
A lot of these tunes are here for the purpose of historic reminiscence rather than a showcase of quality music work. I'd probably cull 90% of these if I were in that mindset. One day I might get around to putting descriptions to all of them for the website, but honestly they're so small, you might as well click and download them.
The most accurate mod player is XMPlay by Ian Luck. If you already have Winamp, it's a good familiar choice, and does a satisfactory job.
