I used to take a risk and buy 7'' singles from the bargain bin, songs that I'd never heard before. Sometimes it would pay off, and end up with a gem that I was thrilled to have found.
Other times not so much. There was a girl, I think her name was/is The Real Roxanne. I thought she looked (on the cover) like a girly pop singer, and was hoping for a StockAitkenWaterman type of track. It was a rap song. Not for me at all.
