As a prog fan, I'm shrugging my shoulders at most of these.
A couple of interesting successes though...
Every Little Thing She Does is Magic by The Police: The first two minutes is the tune - the remaining two minutes is basically an unrelated play-out. Having said that, none if it is flab, it's all great.
Catherine Wheels by Crowded House: The second half is an unrelated jam, and it's all absolutely beautiful.
