I wouldn't call it lesser-known but Doom (2016) 's soundtrack is one of my all time favorites. It's a mix between EDM/Electronic and Metal, it can really get you pumped, especially songs like Rust, Dust and Guts, BFG Division, Vega Core, Mastermind, and my personal favorite, Rip & Tear: This next one is indeed lesser-known in my opinion: https://www.youtube.com/watch?v=W78Z7yz5Mqs Persona 3's soundtrack which is, i would say, a mix of many genres ranging from jazz, 2000's electronic, to pop-ish songs, rap vocals and even rock guitar riffs, on top of that it has a nice mix of ambient, tension and battle songs. The Binding of Isaac: Rebirth, this one is on the unsettling/creepy side with electronic and rock influences: Enter The Gungeon https://www.youtube.com/watch?v=s3GCez8CDJI, this one is an electronic/orchestral 8-bit/chip tune thing, it's pretty cool. That is about it for now, maybe i'll think of more in the future.
