If you have a few favorite genres that aren’t overly common then you could browse Steam tags for them every now and then. I’m really into metroidvanias, so I can take a look at that tag every month or two and see everything pretty quickly.
Thanks for that tip @barakatnull and welcome to the forum.
Not quite new, but still getting some very interesting new content
If you’re looking for more music along those lines, have a listen to BigGiantCircles, who wrote a decent chunk of that soundtrack. His first release, “Max effect”, is made up of tracks that didn’t end up being used in the game, and “Legacy” is kind of a remix of some of the existing soundtrack.
Haven’t listened to him for a while now, probably should check out his newer stuff now that he jumped up in my memory again.
