the band is called pet shop boys, and when you do a search on overture, it doesn't take into account the s at the end, so that 17715 would have been for pet shop boy and pet shop boys. You can be sure that 99.9% of that was for pet shop boys. If your going to sell this based on traffic, you need to slap up a counter, you might get some mis-type ins, but thats it.
Good luck.
