The thing I regret most about modern popular music is the decline of the comic/novelty song.
Don't forget the brilliantly twisted mind of Tom Lehrer; my Dad loved him and we had copies of all his albums. If you've never heard of him, he was big in the 1950's and '60s. The guy not only taught math and political science at top-notch schools like MIT and Harvard, but also played the piano performing bizarre songs he'd written. I was pleasantly surprised to see he's still alive at age 89.
He was the creator of such classics as "Fight Fiercely, Harvard" [a parody of the traditional college fight songs], "When You are Old and Gray" [a guy explaining to his wife why he'll ditch her in the future], "Be Prepared" [a revised version of the Boy Scout motto], and "I Want to Go Back to Dixie" [letting the South know exactly what he thought about race relations in the 1960's]. I'm sure you can find something of his on YouTube.
However, to me the most impressive song is "The Elements." It's exactly what the title implies, the entire periodic table of elements, rattled off in order to the tune of the "Major-General's Song" from "The Pirates of Penzance." How does anyone come up with something like that?
