All music can influence emotions or state-of-mind to some degree, but the lack of complexity in pop music makes it so that this influence is the only "worth" or, perhaps more accurately, purpose of the music. There is nothing wrong with this necessarily, I am just giving another reason why pop and such might be so popular.
Sure, there is that, but let's not kid ourselves, those fruit are popular because they are actually preferred by a vast majority.
If it was not for the music industry. Pop bands would not exist. Boy bands would not exist. Etc. They are as artificil as bananas.

Yes, that works for most people. But if you're seeking new, exciting and different then those recommendations come off as dull and lifeless.
That music never went away. It's not like you're no longer allowed to listen to Pink Floyd. Music doesn't have an expiry date.

Prince refused to perform it after it expired.
I wonder how it's going to play out because generations up to now have shared a relatively small cadre of media offerings in semi-rigid genres; that shared experience has in some ways - at least in the 20th Century - underpinned societal culture.
Shared interest in YouTube stars, amongst many other things, still keeps the thread of share cultural experience in society; but what direction are we going?
If I have a billion different media offerings I can consume the chances of meeting people and having a shared cultural experience we can link over get smaller. Whither nostalgia?
TL;DR, Nostalgia won't be what it used to be.
Everyone, everyone in the industrialised world and well beyond can purchase a device smaller than their palm and listen to literal billions of songs. Noone is stopping you from only listening to "Tibet monk techno punk instrumental remixes" for the rest of your life - without buying anything you don't already have. So can this mother of all substanceless debates please just die...?
