Eh, sounds a lot like an old man yelling at the clouds. I don't agree with the general premise that "music is getting worse."
There's certainly a lot of bad music out there. But there's also a lot of good music out there. It's true that music is easier to make (and distribute) now, than ever before. And that means there's a lot MORE music, in general. More bad music, more good music, just more music.
Basically old people are nostalgic and prefer the things from their youth. Nothing new there, at all.
