Unpopular opinion, people who are like "I don't like modern music" aren't looking for actual good music, they're just listening to whatever surface level stuff is on the radio, and therefore don't even really 'know' modern music.
I mean when people say they like 90s music they don't exactly mean they necessarily wanna blast some nsync, but that's what was on the the radio then. You want good music go look for it. It's the same as it ever was.
Also, people who say they hate rap are NEVER talking about rap, they're talking about trap, they just don't know the difference.
And one last one, learning kanji is the most fun part of learning Japanese.
