PENNSYLVANIA, US: If the music thing doesn’t work out for Taylor Swift, she’s got a back-up lined up - as a detective.  The singer is obsessed with crime shows and spends every waking minute watching them while on the road. She popped in for a chat at the Capital FM Summertime Ball on Sunday night and said if she wasn’t making millions from music there were only two other career choices.  Taylor said: “I’d be an interior designer or a detective - but I don’t think I’d be a good detective. “I just watch all of those crime shows. Anything that has a slight premise of being a crime show, I’m on it. –Agencies
