This Youtube comment basically summarises Pink Floyd for me:
"How many times did you rush out to grab the latest Floyd album, get home, put it on and think, hmm? that wasn't what i expected, not right happy with that. Listen again and think, yeah, i guess it's ok. Listen again and thing fuck it's pretty good really. listen again and think OMFG WOW! and what? 30+ years later you listen to stuff they did all that time ago, the less obvious stuff like this and all those incredible memories just flood right back. That's music!"
