Not really unpopular but I love most pop songs from 2000 to 2015 because pop is a genre i find myself not getting tired of listening to. And Britney Spears songs? Still fire. I prefer old Lady Gaga, Taylor Swift, and Marina and the Diamonds though.
I like vocaloids but im ngl that I listen to covers of it 80% of the time. The only voices I like are Miku, Luka, Gumi, and Gakupo v.v I can't stand too high voices at times with most songs in them. I really don't like Kaito's voice except in this https://www.youtube.com/watch?v=0HAFjnOF77Q
also don't get it when people say nowadays songs are all about s**, like even before most songs were about it, it's just that many were young to understand what the lyrics meant lmao.
