Not as much of a difference as you might think. My taste in music is very, very broad. I love the artists you mentioned.
I also saw Pink Floyd twice in concert. (Sadly, not with Waters though.) They have always been my favorite. Floyd would be an incredible halftime show! Better than the Stones.
I didn’t mean to imply that either girl put on a good halftime performance. But they can sing.
According to some "experts", one tastes in music are formed by the age of 16 and then are set thereafter. If so, nothing after 1959 would appeal to me. I don't think that's totally true since artists such as Roger Whittaker and Karen Carpenter both rose to fame in the 1970s and are easy on my ears. Still, I think the ears become used to certain genres and reach a comfort zone whereby new musical forms (such as hard rock, in my case) become unappealing.
Since you mentioned your broad musical tastes, I think you'll like this one featuring Ft. Worth's Tex Beneke: I've got a Gal in Kalamazoo.
