Best singer?!

Among the strangest things on Facebook is the "Compare People" application. Because people rank me compared to other friends (and I rank them), "Compare People" is able to come up with stuff like this:

Your friends have voted on your strengths and weaknesses:

STRENGTHS:

best singer
most trustworthy
most likely to succeed

WEAKNESSES:

most adventurous
most artistic

Best singer?! Do I really have that many friends on facebook that don't know me at all? Or do I have a talent I didn't know of at all?
