So here's what I think happens, Motown, Stax, Phil Specter, and Joe Meek remain popular throughout the 60's and Rock music just becomes big band music 2.0 because those crowds were already using a ton of people in studio to get a very big sound.

I think you can get a full version of Poker Face, it was released as dlc for the Rock Band series.

No it's different than that, the issue is that Pete doesn't put as much effort into the stuff as he used to because it burnt him out on doing so (post Quadrophenia) and because of the type of band the Who is they have to make new stuff that fits with the old stuff and they can't really go fuck around and experiment…

I'm guessing Pete is a fan, remember he's been playing with synths for a majority of his life and he's done dance music as well.
