But hell it's your track, and it's my choice to download only tracks with sensible screenshots...
Exactly.
It's the author's choice whether or not s/he want to make a screenshot of a track or something unrelated.
It's the people's choice whether or not they want to download a track with a screenshot of the track or if they don't care.
It's the author's fault if they get fewer download because of their screenshot.
It's the people's fault if they miss a cool track because of a screenshot.
But goddammit, why make a stupid rule just because people can't make their own choices, whether that's good or bad idea...
