Probably It's 'Orrible Being In Love (When You're 8½) by Claire and Friends, which I genuinely did like at the time, but in hindsight it's a bit, well, a wee bit embarrassing (mind you, the b-side's worse). I mostly listen to it when I've set my iPod to play all my 7" singles in order and it gets far enough through it that that one comes up (which doesn't happen often, as it's track 96 out of 570). I make no secret of the fact that it's in my collection, but I don't share it with people. Unless they really really want to hear it.
I have tracks in my collection which I find perfectly acceptable, but for some reason when I share them with my friends they object. They say I'm "inflicting it on them". *cough*takingthehobbitstoisengard*cough*
