If it was me, I would change it to something like:
* https://chiptune.app/browse/Contemporary/Virt
... opens the browse folder, as it does now.
* https://chiptune.app/browse/Contemporary/Virt/v-choppastyle....
... opens the browse folder _AND_ focus/selects the given track.
Of course, neither one should play anything by default, but! I would put the play controls on the top of the page, and make the play button bigger and more prominent. It took me a while to find the tiny triangle in the bottom left of the page.
My 2 cents. Awesome project btw! :-)
