I like any of the Nujabes albums. He makes chilled, mainly instrumental, hip hop music.
Something semi ambient, preferably without lyrics: Tycho, Bonobo, Nujabes
Here’s a tip I picked up somewhere. Make a playlist. An hour or two worth of music. ONLY listen to it when you’re studying. I’ve found my brain just blocks it out after a few times through, but it triggers my subconscious or something. As in, if I’m not feeling like studying, I put it on and my brain just goes,“OK, it’s time to study.” I change it up when I’m starting a new long task (writting a new book, starting a new semester, whatever). At first, I find myself listening to it, but it doesn’t take much repetition for it to fade into the background.

I think this is a really good answer. Just search for a focus playlist on whatever platform and let it run.
If I’m picking out music more specific, I find myself thinking about that, and what it’s like, and if it’s helping, and maybe I should hey this other album or artist.
Don’t let picking the music distract too much from focusing on what you want to do.
