Would you be shocked if I told you I have an addictive personality? No. Didn't think so. I can get obsessed with nearly anything.
As my flatmates are no doubt painfully aware, this includes music. If I find a song I like, I can, and will, listen to it many many times in a row. I believe in being upfront about these things; I have a totally bizarre, and mostly atrocious, taste in music. Last week I listened to a remix of Cazal's Somebody Somewhere ten million times in succession; the week before, it was Hadouken! Declaration of War. I like bad electro, very much. (See also: long-term love-affair with Basement Jaxx).
I also adore Britney. Sorry. I had a couple of days last week where all I listened to was Nelly's Ride With Me. As I documented at the time, Bon Iver's Skinny Love got me through many dark dissertation hours. Pop, crap R'n'B, and average acoustic emotional wittering. I should be mortified if you saw the i-pod play count for My Chemical Romance's The Sharpest Lives or Blink-182's A New Hope.
I wouldn't be, though, because I own something even worse. I have a piece of music so terrible, and so utterly ridiculous, that it beats Ms Spears without batting an eyelid.
If I tell you mine, you must tell me yours...
my worst musical obsession ever, and one that I still keep on my i-pod:
the theme song for the anime cartoon Sailormoon, in English.
