I'm totally with you there. Electrolytics are convenient for where super large size capacitors are needed, but best used where their inherent non-linearity isn't a problem. That pretty much rules them out for any kind of analog audio circuit.
And I also agree with you about polypropylene capacitors. These days, poly caps are available in fairly large sizes. Anywhere I see 1uF to 100uF electrolytic caps in older gear that I care about, I immediately swap them with polypropylene capacitors.
