I'll throw up a poll shall i?
Down.
Check out this Axis of Awesome video where they lay down the music at it's basic core. All of the songs in their own original form are actually pretty amazing, but this makes them sound like a piece of crap lol.
Lol. I love that video. We watched it last year when we were discussing intellectual property rights and whether anyone could try to patent that chord progression or any permutation thereof.
The answer is more or less no.
As one of the masses, I have to agree with spink's assessment. Music that starts getting too complex doesn't sound good at all in my ears.
