"Doom-Jazz" takes the tempo and... doom-y-ness? of doom metal with the instrumental, chords, and ambient aspects of jazz. It's a lot like "Noir-jazz" like played in old movies, but even more down tempo and ambient like.

"Tape Loops" is a more difficult genre to describe, mostly because I don't know a lot about it. At least a majority of the genre is about using old, analog tapes to record music and "loop it" by taping a small section together and then playing it over and over and over, with effects or not. William Basinski's "Disintegration Loops" is considered the height of the genre, and is devastation in its musical palette. It's divided into six movements each between 20 minutes and an hour, with most of them being closer to the hour mark. At first you almost want to turn it off or laugh at the "boring" super-repetition, but then the music changes, and the notes get inside you. The music literally decays, the old brittle tapes fell apart, and bit by painful bit the music dies. I could talk about it for half an hour on how amazing the music is, how sorrowful. The notes that fade away quickly, the notes that remain till the end, how long you think the last minutes might last, so painfully do they hang on. Each loop does this differently, with no. 6 being the most peaceful, almost like credits rolling after a movie, to the 4th movement, that rips itself apart.

"Future Funk" seems to be a lot like "vaporwave" that ironic genre that's like plugging a synthesizer into the internet. Future Funk is an offshoot of vaporwave too, with snippets and jazz influences too. It's weird, but different, a lot of stuff online, although I wouldn't recommend using streaming services to find it.

Thanks for the congratulations! I use the font "Old LMBs", so I see the old ranks too.

No, it is more of a down-tempo jazz, so it's not really suspenseful, although it does create "ambiance" or atmosphere. Slower the better, like darkly brewed coffee.
