This also links to Datashat's own Businessfunk compilations, which are excellent on another level from your regular ambient: http://datassette.net/businessfunk/
But as heavy-artillery concentration music, I recommend TechnoLiveSets. It's the ‘accidentally done all work in one day’ grade material: https://www.techno-livesets.com/
P.S. I'm also gonna gripe about lack of volume controls on the site, which for some reason a bunch of sites consider acceptable. All volume levels on my machine are carefully tuned—and then this site comes along for which I have to fiddle with the master volume. While listening to this explicitly background music, I'll likely come across some videos that I'll want to watch for ten seconds—and then I'll have to either crank the video volume, or scramble to stop the music each time. Don't do this.
On top of that, site authors' ideas of proper volume pretty much never matches mine: Bandcamp and Soundcloud both have to be cranked down a lot: Soundcloud's embedded clips make me lower the system volume to 1/4th of a notch on my Mac, which is about 1/32nd the normal volume for me.
Holy shit! Businessfunk 4! And on Resonance FM, no less. How was I not aware of this? You've just made my 2019.
I love Businessfunk to the extent that I am prepared to name it as my favourite genre of music.
Datassette has tracklists on Soundcloud (iirc), and Andy Clark, Keith Mansfield and James Asher seem to dominate his mixes (though Asher is apparently more into tribal music). Alas my favorite bit from Businessfunk 2 at 34:25 is unidentified.
And btw, there's also a fourth mix for the Near Mint web radio: https://www.mixcloud.com/Resonance/near-mint-8th-march-2016-...
