You don't mention The Beatles, Led Zeppelin, and the 100's of other artists that Spotify streams millions of times. I feel DIY punk music and music that is "insanely easy to produce" is not going to make much of a dent in the massive demand for the classics/popular bands. Also, as a musician of 20 years having recorded multiple records, I don't agree good music insanely easy to make. The plethora of mediocre music out there is not good music, it takes a lot of skill and equipment to make something sound good in the studio. Sure, maybe some folks want a DIY underground sound that's not polished, but the average folks out there want a clean sound, that's what sells/drives listens. Just go on the Top 100 spotify playlist, there's basically no DIY stuff on there, its all the poppiest of the pop, heavily produced.

Do the young really care about the back catalog anymore?

I'm not just being snide. Think about Elvis. When was the last time you heard something from Elvis on the radio or in your stream?

It's definitely a sliding window. Elvis is not so important but stuff from the 1970's to the 2000's remains popular with kids.

Heuristic: parents pass on their teenage music preferences to kids but don't pass on their own parent's teenage music preferences to their kids?
