Basically how much you listen to non-vocal synth songs and vocal synth songs.
For me, I used to listen to half non-vocal synth songs and half vocal synth songs back when I first joined the fandom. Before I did though, I heavily relied on non-vocal synth songs. Now I don't usually listen to vocal synth songs as I used to, but there was 1 vocal synth song that I scrobbled on Last.FM: Kagerou Days by Jin.
So, basically, I am 90% non-vocal synth songs and 10% vocal synth songs as of now.
