Unfortunately no, I don't have a playlist that I could share or recommend in good faith, not at the moment.

But if you mean more generally, just, what do I listen to, to help concentrate?

Hrm.

Various chiptuny, melodic beep bloopy music... sometimes things with rolling or constant bass or drum lines or something... 'Conga Fury' by Juno Reactor, 'One of These Days' by Pink Floyd, or 'Tick of the Clock' by the Chromatics...

But, sometimes much more laid back and chill stuff, lounge background music type stuff, throw some hip-hop stylings and you end up with something like Nujabes, or maybe RJD2 (though he often uses so many vocal samples that those songs can be distracting), ambient electronica, Boards of Canada type stuff...

Sometimes various classical songs.

Sometimes literally Mongolian throat singing, which I guess does not register to my brain as speech.

It depends on my mood, lol.

And also the ... level of instensity of what I'm trying to do, whether or not its very physical, very mental, or both.

Going even further, a decade ago now, I actually tried to see if I could find some kind of actual... threshold, where my brain, or I, whatever, can't really decide if its 'vocals' or not, in terms of 'does this mess with my ability to concentrate.'

And that is how I ended up finding TOBACCO / Black Moth Super Rainbow.

... Nobody really sounds like them.

The way they make their sounds, you'd think its digital, but apparently its all analogue... they have a very strange way of ... making, and then using, some kind of vocoder.

... I would basically describe the music as what a good LSD trip ... sounds like.
