In a Space Outta Sound by Nightmares on Wax
Bonobo - Dial M for Monkey
I like any of the Nujabes albums. He makes chilled, mainly instrumental, hip hop music.
Not really a album but MyNoise.net has a lot of good generators for background noise. Radio Free Fedi’s Comfy channel also is great for chill study music, and it only plays indie artists that have Fediverse accounts with links to the artist support pages where you can either buy their albums (or songs to build your own piecemeal) https://radiofreefedi.net/.
Any rando lofi channel on YouTube/Spotify/Online Radio Stations
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.
