Is this any more up your alley than Whip It by any chance, or no? Also, suggesting an avant-garde song only became popular because people liked the also avant-garde music video is a weird, contradictory argument. The band had already gotten some mainstream success before that song (they had played SNL and such).
The problem with all this is that you're trying to change the definition of avant-garde from its widely known meaning to "only music I dislike can be avant-garde, and any music that I DO like is automatically not avant-garde" where you're basically creating a completely self-sustaining bias that all avant-garde music is completely unlistenable trash. Can are avant-garde, and you like them, Devo are avant-garde, Good Vibrations is avant-garde, and the latter two have both had tremendous mainstream popularity.
