Pink Floyd is one of the most popular artists of all time. When the "Dark Side of the Moon" album hit in 1973, it was played over and over again in dorm rooms and apartments everywhere. It was from a time when deeper meaning was valued, and they hit the nail on the head at the perfect time with that album. Incredibly, it was on Billboard for over fourteen years selling over 40 million copies!!!!! Their guitarist David Gilmour is considered by many (including me) to be the best guitarist that has ever walked this planet. Their list of albums and hits that followed is staggering and they have sold over 250 million records! They are on every list of greatest bands of all time, and were inducted into the Rock and Roll Hall of Fame in 1996. Oh yeah, they won some Grammy's too.
