I really doubt The Beatles were the first band to write their own songs, nor were they the first to experiment with sounds and instruments in the studio. The Beatles get credit for it because they were the most popular to do it, but I really, really doubt they were the first.

While The Beatles were the driving force in "popular" music in the sixties, that doesn't really encompass Pink Floyd. The two bands, while rock groups at their base, are vastly different in basically every way possible. They didn't write the same kinds of music, didn't play the same kinds of music, didn't have the same aesthetics......the only thing the two groups have in common is they're both British.

They're just too soft and namby-pamby for me. Like I said, they did some really catchy tunes, but on the whole I don't like listening to them.
