To further elaborate on my post above: I like Floyd a LOT, but I cannot claim to be a hardcore fan at all. It wasn't until the early '90s that I finally broke through and became a fan, so I was VERY late to the game. To this day, I only have about half their albums, and do not recognize a good many song titles from the albums I don't have. So that said, I realize that any "favorites" list of mine is going to immediately stand out as a list from a casual fan.
But that being the case, when I look at my favorite tracks from them from the '70s, I would be hard pressed to name ANY other band from that time period that gave me so many songs that I like this much. It is an incredibly strong list, and includes (chronologically; not ranked):
-One of These Days
-Echoes
-Pretty much ALL of the Dark Side of the Moon album (On the Run is usually a hard skip)
-ALL of the Wish You Were Here album
-MOST of the Animals album (I don't have it, and sometimes get the songs confused)
-In the Flesh?
-Another Brick in the Wall, Part 2
-Hey You
-Comfortably Numb
-Run Like Hell
I definitely have some other bands where I can generate such lists spanning certain decades. But there aren't a whole lot of them. Floyd really put out a lot of great stuff in the '70s, even if there is still a lot that I don't know well or don't connect with. For Yes, I can't even remember any of their songs. But what I do remember is that when I heard their stuff, I would generally just tune out and not be interested. So: about 4 full albums worth of material that I really like vs. zero songs that I like. Floyd easily wins this poll for me.
