Point Faircamp to a folder hierarchy containing your audio files. Within minutes, Faircamp builds a complete website presenting your work. The resulting site requires no database, no programming, no maintenance, and is compatible with virtually every webhost on this planet.

I don't actually have much interest in this particular project for myself, but I have a half-baked start at the same thing for my photos, and this site is basically built the same way, so I'm linking it as an inspiration.
