"Try "every song U2 ever wrote is based around the A scale".
And you know what? They sound really good!"
But there's enough stuff that just sounds half-decent or even "good" on the radio nowadays. Whatever happened to originality and musical talent? Well, that wasn't a rhetorical question. MTV has destroyed such things by slowly making music more about the image than the music itself. Mainstream music has progressively become all about looks, and conversely, creativity in the mainstream has progressively gone downhill.
"The reason the mainstream is referred to as a stream is because it's so shallow."
-George Carlin
