Well, you musicians should be happy, because it looks like someone *did* go and make a music player. Here's a demo. This is Scritch, a new web player for itch pages, and it's a perfect fit for this thread. You can read about it on twitter here:

and there's an easy itch page to build your own here:

In my opinion this one has a few benefits over other linked alternatives in this thread, so there's that.
