Every generation thinks their music is the best.
Even the Millennials think that RAP/Hip-Hop is best.....................
Millennials don’t like hip hop really. They are into emo-rap, crunk-core, emo-core etc... Millennials and zoomers love to be very specific about their music genres and taste.
Not all of them
Most I know prefer the quality of Rock
63-late 90s
Most everybody knows well the music from when they were young (in my case small child in the 70's, teen in the 80's). And most everybody knows some of the music from before they were born (in my case 50's and 60's music). But I would assert that the Millennials and Gen Z'ers can quote 1980's music (from before they were born) better than any other generation can quote music from any decade before they were born.
Evidently, 1980's music is the most popular, so popular that my grown "kids" and their pals know it about as well as my wife and I do, way more than I know 50's and 60's music, and way more than my parents knew music from before they were born.
Pretty sure that 70-80 yr. old Millemnials will NOT be listening to that RAP CRAP!
