I am looking for some opinions from people who were around when Pink Floyd was in their prime, specifically the Big 4 albums [Dark Side of The Moon, Wish You Were Here, Animals, The Wall]. I am 31, and have only recently delved into their work. I was too young to be there during this period. I barely remember The Wall. I never got into their music at the time, because I always thought it was "stoner music". Listening to it now, the one thing I can't figure out is: How did they ever become commercially popular? I am not talking about the quality of the music. Their music is so introspective and thought-provoking that I can't imagine how it ever became commercially popular. Most of their songs are complicated, dark, and depressing. Sure, they have a few "Top 40" songs such as Money, Comfortably Numb, Another Brick in the Wall, etc. But these songs are definitely in the minority. This has continued to confuse me, especially since this apprarently was the time when "Corporate Rock" began. Was it the drugs? Enlighten me.
