I tend to gravitate to music without lyrics.

I've been listening to a playlist I found on Spotify - "Beats to think to"

Also, if you like the sounds of a coffee shop, checkout coffitivity.com (no affiliation). If I'm in the right mood, gets me in the zone.

I think no lyrics is key! Instrumental tracks are less intrusive and have a lot of repeating patterns.

I completely agree!

I think it is the acoustic equivalent to the Clippy effect: Human voices tend to take up a substantial portion of our mental bandwidth, because it is not just a sound our brain has to recognize, but then it has to go and actually understand the words being said or sung.

Instrumental music tends to have - at least on me - the opposite effect, it occupies the parts of my mind that otherwise might distract me, leaving the parts doing the hard work alone.
