Yeah it was a bit weird, she doesn't like any music???!!! According to her intro bit, she finds it a distraction.

I really couldn't get through the day without a bit of music, especially sitting in the car in traffic on the way home from work... other drivers must think I'm a nutter sitting in the car head-banging and doing air-guitar!!
But Lesley seems a strange type anyway, good potential for a BB housemate!
