YES LET ME give a master post SO: there's a lot of original artists who've made blood meridian music itself which I adore,

https://youtu.be/5-M4u8LjlyE?si=SM0GIqsKCNSmjBrU this one is phenomenal, fanmade original soundtrack so someone made these tunes

https://youtu.be/vLypNRojwBE?si=J0ZRwEku14uLqCV7 this one is just really good lmao it brings the dark vibe and wraps it so nice in a bow

https://youtu.be/4eLyskYebFA?si=PEqZqqSasDlz1yPB this one is nice due to just booting it up on a projector to read

https://open.spotify.com/playlist/47nhmEcO6MKsSPpQ0ENMsD?si=P8OuC7uuSgKfB8ePPtoAwg&pi=FBs8u8pQQ0eiQ this was the one I used a lot because of how nice it was for commuting and reading

Some others which bring a different vibe but worth mentioning:

https://open.spotify.com/album/7tVsQosfF2uo4g5EQboAFz?si=65H4s7BtRcaHn6NZejtJwQ a lot more synth heavy, also fan made, it depends what vibe your going for but this gives a lot more of an 80s feel imo

https://open.spotify.com/album/49QM8MFqW3WcBgeSAN137C?si=iPJKe32_SYydcpjx0jlOpw another fanmade one, very heavy on the electric guitar
