If there’s no Kraftwerk it’s not “perfect”. It also seems quite modern - there’s lots of instrumental music in all sorts of genres or periods that works. Hell

If there’s no Kraftwerk it’s not “perfect”. It also seems quite modern - there’s lots of instrumental music in all sorts of genres or periods that works. Hell, people can go all the way back to classical music (or it’s modern reimplementations such as switched on Bach). But I agree that voice must be limited. I can debug to most instrumentals but it seems my mind tracks voices and thus distracts me.
