Yeah, I guess my perspective on Pink Floyd is somewhat non-mainstream, since they've been a favorite band of mine since Piper at the Gates of Dawn, not to mention being a musician who's covered their stuff in bands since Meddle. Being AOR they didn't benefit from the singles sales mentality.
Related note: I've always considered a "One-Hit Wonder" band to have two characteristics:
- They had one hit record
- They basically disappeared from public awareness after that one record
OTOH, if the band was around before the one hit, and kept going (e.g. in AOR-land) for years/decades after the one hit (like Floyd), I don't think it's the same thing at all. But that might just be my perspective.
Pink Floyd is my favorite band, too. Piper at the Gates of Dawn was long before my time. Back when I first got into them in the 1980s, I was warded off from their pre-Dark Side stuff by being seriously underwhelmed by Masters of Rock: Pink Floyd’s Greatest Hits and Ummagumma, plus even the band’s own dismissiveness towards their early work. Just a few years ago, now that streaming means you can hear an album without deciding to buy, I’ve rediscovered their early stuff and become like a teenager about them.
