Chillstep or lofi for focus.

Sublime and the like for cleaning.

I've had the Billie Eilish's new album on loop recently. But before that I'd usually have some Floyd or god machine on.

Found this playlist on Spotify recently called Creative Flow Music and it is now my go-to.

Soundtracks to puzzle video games. Spacechem and the rest of the Zachtronics games have Great music that helps encourage concentration in my opinion.

Been on the lofi Chopin and similar songs lately.

I have the ADHD and unless it's a mindless task, I can't listen to music or it makes it much harder for me to concentrate. For anyone else with the disorder, I'd encourage you to at least give it a shot working WITHOUT music and see if it improves your concentration.

Psytrance is ideal. Designed for dancing yourself into a trance, perfect for energetic flow state concentration, like studying.

well not for concentration, but my ambient music is a mix of lemon demon and rain world
