I listen to Sega Mega Drive playlists. Usually the relaxing ones. I've played them so much that the song progression is normal to me. I know which one will play next in the list. Sometimes a song gets stuck in my head and it impedes my thought process, so I put it on and don't have to think about it anymore. Usually the Sega songs, they are designed to be repeated.
Check this one out, just let it play until the end https://youtu.be/KrOayhOn-tw
