I completely understand. If you're not a fan of the artist, you saved yourself some money by turning it down. I probably would have done the same as I'm not a tux kind of a guy. Here's a good way of thinking about things like that. By turning it down, you just gave someone else a prize! Normally, unless it states otherwise in the rules, they conduct another draw and award it to someone else, so in a very real sense, by turning it down, you made room to make someone else happy and that's awesome.
