Those are the chances you take. It doesn't happen everyday, but if you keep it up long enough, it does happen eventually.
Plus, if we decide to chance it and just play anything at all in the shop, then the other staff will pick the songs and frankly, they all have rubbish tastes. This way, I get control.
I absolutely refuse to listen to music chosen by fans of say, Fallout Boy, or people who think that Metallica's version of Whiskey In a Jar is superior to the original.
In the meantime, I am playing various radio podcasts without music.
