I haven't seen it mentioned here, but Bassoon Tracker is a web-based tracker that can play most old MOD, XM, etc files: https://www.stef.be/bassoontracker/

There's a few demo-mods along the left side, several mod archives listed in the File menu, and you can load your own as well.

That and I figured out you can actually use it to compose your own tracks if you like, just like the old days!
