Seems like people either really love or hate Belle and Sebastian too. There's really no fine line there...you either like what they do or you don't. Personally, I think they're great.
I think back in high school it was really a battle of who liked metal vs. who liked hip-hop/rap. Then there was me, the lone freak who hated both and listened to the Pixies, the Stone Roses, Sugar, the Charlatans UK, etc. and got a ton of shit for it. I will never forget that there was a big angry fight one day about Vanilla Ice vs. 3rd Bass. Ha! I also remember the arguments that kids got into that were into Metallica and Megadeth vs. the kids into Black Sabbath. Then there was me...going to see the Jesus and Mary Chain w/Curve and Spiritualized. Sigh, those were fun days.
