I had a student about 6 years back who turned me on to them, which is very strange because most of my students don't give a single shit about music. I mean they say they do, but when you ask them to specify they like ringtone pop, in Chinese.
So getting a bona fide 'I'm into midwest emo, I can tell you how that is specifically different from other emo' got a huge 'thank you!' from me.
By way of contrast, Japan is super into music and you find people really into niche stuff everywhere. People being incredibly into The Stray Cats or dub reggae or something.
So to cut a long story short, I'm not a big American Football fan, but as soon as I see their name I have this 'fuck yeah!' reaction, because it's forever linked with finally finding someone in my class who could speak passionately about music.
