No, it isn’t. It’s more an observation that pop music is so banal and idiotic that a group of 70 something-year-old men are still better.
Honestly, it should not be that way.
The old rock and rollers were oftentimes very good musicians. Some like the “Moody Blues” and “Emerson, Lake, and Palmer” were classically trained.
They may have been dopers but they were educated dopers who really worked at their craft.
“... really worked at their craft.”
Crackerjack point.
Nowadays it’s way more about marketability, than craft.
