Every musical generation suffered from sounding the same
I get that modern music gets crapped on a lot depending on the genre or artist.
But to be fair, everything sounds the same and always have. when my grandparents listen to their "golden oldies" music channel that covers the 50s, 60s and 70s. There is a very clear decadal sound to each, or at least a clear segmental generational grouping as one bands sound influences the whole genre. and they all end up sounding similar and generic.
and lets be honest their lyrics (with some exception) even for the greats, were hardly revolutionary or genius. theres a reason "baby" is the most used lyric in songs I believe, followed closely by love.
when watching a show like americas got talent my grandad complains "oh my god they all sound the same". then I ask him if he listens to his own music?
A lot of the greats weren't that great and for me this is epitomized in bruce Springsteen I know its subjective but Bruce Springsteen is downright horrible at times. Everything is about jersey, that girl you brought for a ride, the turnpike. Its all theatre, all energy, all bang, but really pretty generic lyrics about things he never experienced.
as one person said "it was blue collar music for white collared middle age men who never experienced any of it and take their Camaro out every Sunday to drive"
