Battle of the bands??? (members, song, guitar, Organ)

[DontRunMeOver]

So, my band have won numerous 'Battle of the Bands' competitions, and here's how.

We turn up at practise and I announce to the other band members that today we are having a 'Battle of the Bands' with our band competing against all of the other bands in the practise studios. Obviously, I only tell our band this.

We play our little hearts out and boy do we play well. All of those listening (only us, most of the time) like what they hear and surprise, surprise, when votes are collected (only we vote, of course) it is announced that we are the winners of the Battle of the Bands and we each recieve an Irn Bru as a prize.

My question here is, how is this any less biased or insignificant a result than any other 'Battle of the Bands' competition?

Answer me!
