In case anyone's interested, here's a sneak peak at a little project I'm working on. This is essentially a script that creates an HTML-based music catalog, based on the ID3 tags in a collection of MP3 files.
The link above leads to the output from a very alpha version. Once I'm done, I'll like to a package, and tell you how to run it, and so on.
There's a lot left to do: make it so all the various collections show up as the same album, translate non-ASCII characters properly, create some nice-looking CSS, and so on. But for now, I'm pleased just to get these early results.
Enjoy.
