One of the few benefits of being old/decrepit is the ability to remember this stuff. That Pearl Bailey song in seg. 1? I heard it when it was released. This applies to most of the older material I play. Some of the show's best stuff comes directly from internet radio...like the kind we have here. If you look around, every genre has internet stations dedicated to it. Especially Xmas. You hear it, Google it, snag a copy. YouTube provides an endless supply of it. (not that we advocate piracy or anything...oh, wait...)

As for the other, I've been saying "today's music sucks" for decades. In the '90s, "grunge sucks." In the '80s, "hair metal sucks." In the '70s, disco (obviously) sucks." Before "Rubber Soul", I thought The Beatles were just more noise. Then they started writing their own tunes - and all of modern music changed.
The dealership fried my car CD player & wouldn't replace it, so for a while (before I rigged an old 4th gen iPod to it), I had to listen to the actual radio. Hoo, boy! What a steaming pile! At least the disco artists could actually sing (mostly). Just search for "Millennial whoop" and the core of the problem is right there...along with Auto-Tune.
"No-talent bastards", "pre-programmed dreck" & "uninspired crap" doesn't even begin to describe today's music. But then, every generation thinks the music we heard when we were young is better than the turd sandwiches they dare to call songs today. The difference is that unlike before, this time, we're right.
