I will challenge this a little. Don't disagree that generations have different taste. But most Gen X that I know liked everything from rap/hip hop to metal, country, rock anywhere from the 60's up, etc. I still listen to everything from Elvis to Pink Floyd, Zeppelin, Jerry Lee Lewis, NWA, Enya, Keith Whitley, etc.. Pretty diverse and I think most of us appreciated must from any generation. That is until the 2000's when this horseshit country started to kick in, rap because unbearable and rock pretty much has been lost for the most part with the exception of a few new bands and old farts putting out new albums. My son is 21 and has migrated completely away from new anything back to the 80's & 90's metal, grunge and old hip hop. I am ever hopeful that we have a future generation of Metallica's and NWA/Ice Cubes/2 Live Crew's, but time is running out. Lol. Anyway, just maybe a different perspective but it does seem like Gen X offspring are more into Offspring than Kendrick Lamar's lame halftime show.
The main thing is music is subjective and there’s no right or wrong answer.
Every generation thinks their stuff is the best, the new stuff sucks in comparison and opinions on stuff older than one’s self are mixed. For example, I enjoy a lot of 60s-70s rock and country but think the Beatles are just OK at best. (Yes, I understand and appreciate their influence and impact. Their music just isn’t for me. Please don't murder me younger boomers/Gen Xers of CatPaw.)
Similar to how I put 80s and 90s artists on a pedestal but my 20-year-old niece who enjoys modern pop and hip-hop thinks it’s just old people music as she so rudely puts it.
I would also be willing to guess more 20-30 year olds are into Kendrick Lamar in 2025 than the Offspring. Could very well be wrong there, though.
