something without lyrics
None. I’ve tried everything from Mozart to Metallica, and any kind of music playing while I’m trying to concentrate is more of a distraction than a help.
Surprised to see it’s not mentioned here. 24 years old internet radio, still kicking, over 30 channels with hand-picked playlists, almost all of them suitable for concentration. They are sponsoring Def-Con for years. Owner has a great Fediverse presence.
Channels have very interesting concepts like Spy Jazz, Ambient over NASA’s mission broadcasts, Celtic Folk, Vaporwave, 80s Synthpop and my favorite SF 10-33 Ambient over San Francisco Police Radio live feed.
Synthwave, Post-Rock, Post-Metal, Shoegaze.
It’s what I mostly listen nowadays anyway.
