Yeah, sorry, a bit bad choice of words. What I mean was what @WindcryMusic also said. It's surely not about 3-chord song couldn't be good (hell, my favourite genre of music besides orchestral has always been black metal since 1995 :D ) but the fact that laziness isn't an excuse.I don't know about "better" necessarily. I think a good pop song or three chord rocker can be as good as anything else.
But it's not what inspires me creatively for my own music.
