All of these songs are rock. I am not sure how obscure the Spanish songs are in other parts of the world because I live in America. And most of these songs are not that old, they are all mostly from the 2000s or 90s

So any genre? No specifics? Also, how "old" is old?
Eh anything before 2005 but after 1960.
You got it, boss. I'm not sure how many of these you'd say are totally "obscure", but I'll see what I can do. I may bend the rules a bit for stuff that's pre-1960 that slaps and I'll include some honorable mentions for stuff post 2005 if it fits the bill. If I think of more, I'll add more in a new post. If you want some super niche stuff, like Greenlandic metal (or really metal from different pockets of the world) or hip-hop, I got you covered.
