I agree. In my teenage years we loved Pink Floyd, Supertramp, Genesis, Gentle Giant, ELP, ELO, King Crimson and the more commercial Led Zepp, Deep Purple, Black Sabbath, McCartney, Bowie, Frampton, etc. Most students hated Disco.
Musically there was two clans in my Polyvalente. Half said Pink Floyd was the best group and another half said it was Genesis (the Peter Gabriel years). The psychedelic experimental Pink Floyd vs the best progressive rock Genesis (also experimental). Led Zepp was still very popular but they were starting to be an old group or not the most innovative musically. But everyone loved Supertramp. Someone told me only in Quebec Supertramp was that popular.
