I got this off another board.
If you ever needed yet more proof of the incredibly generic songwriting that creates 'radio smashes', then check this out. It's two Nickelback songs mixed together, one in the left channel and one in the right ("Someday" and "How You Remind Me")
I remember sitting next to the radio as a kid and predicting where chord/key changes etc would happen in a song, and nearly always being correct; and I'm well aware of how simplisitic modern succesful music is, but this is actually quite scary!

One of the things that sticks in my mind about learning music was the moment I was told that the reason that 90% of people won't like a piece of music is simply because they don't understand the conventions, be they structural, melodic, or harmonic, of that particular genre. That's why most commercial rock bands stick rigidly to a very specific formula - and the ones who do mess around with it a bit and still achieve some commercial success (e.g. Wilco, R.E.M. earlier Radiohead) still retain most of the harmonic, melodic and rhythmic conventions of their genre. It's like when a band is successful and 'different', they aren't really
that different.
I just said to my mate, 'Try doing that with two Zappa songs', although apparently Zappa did use to get half the band playing 'Black Page pt.2' under 'Ya Honza', and apparently it worked 'quite well'. Given that Ya Honza is in 5/8, I'm guessing its not quite as smooth as Mr. Kroeger and co!
