Define "new music". Just because it's "new music" doesn't mean it's "pop music". And just because it's "old music" doesn't mean it's "good music" and/or "pop music".
Anybody heard of King Crimson? Or a Yes song that wasn't "Owner of a Lonely Heart"? Mahavishnu Orchestra? Gong? Camel? Jeff Beck? Return to Forever? UK? Jan Hammer? Tangerine Dream?
Those are the "who the hell is that" bands that my parents listened to, which I inherited as part of my tastes in music. There's a lot of good 70's prog-rock bands out there, but that doesn't mean that good music isn't getting made today: Dream Theater, A Perfect Circle & Tool, Joe Satriani, Ozric Tentacles, or diving into other categories of music: Atomic Fireballs, 2 Bit Pie & Fluke, Thievery Corporation, Soul Coughing, Curve, Frou Frou & Imogen Heap, Pepe Deluxe, Coldcut, Hooverphonic, Jami Sieber, The Knife, Republica, Apparat, Jello/Bola, UNKLE, Orbital, Bowery Electric, Plaid, Red Snapper, Leftfield, Underworld, Way Out West, Deepsky, Amon Tobin (Da Man), Squarepusher, Juno Reactor, Eat Static, Cydonia, Lamb, Talvin Singh, Mocean Worker, Boom Boom Satellites, Hybrid, Lunatic Calm, Overseer, Propellerheads. Heard of any of those?
There's a shit-ton of undiscovered music from bands that never see a radio hit. And just because it's on the radio doesn't mean it sucks. (They play bands like Tool, Soul Coughing, System of a Down, etc.)
You also seem to forget all of the old 60-70's bullshit that was played on the radio: Boston, Alabama, Bob "Is that even a fucking language?" Dylon, Abba, Village People. Three Dog Night, Bad Company, Hall & Oates, Kansas, Meatloaf, The Commodores, The Osmonds, The Partridge Family, The Jackson Five, Styx (*shudder*), Foreigner, The Eagles, The Carpenters, Chicago (and every other band I haven't named that is the name of a town or state), Bee Gees (ugh), Neil Fucking Diamond.
Rosalina: But you didn't.
Robert: But I DON'T.
Rosalina: You sure that's right?
Robert: I was going to HAVE told you they'd come?
Rosalina: No.
Robert: The subjunctive?
Rosalina: That's not the subjunctive.
Robert: I don't think the syntax has been invented yet.
Rosalina: It would have had to have had been.
Robert: Had to have...had...been? That can't be right.
