This is fascinating. Of course most modern music is generated with click tracks, if for nothing else than it makes it easier to edit in Pro Tools, since each track will be aligned with a beat grid, and you can literally cut and paste entire bars of music.<p>This has more to do with the modern way of generating music - get four or five takes of the song from each musician, take the best bars and phrases from each one, and put them all together. Maybe Britney had a great take on the second take of the chorus, so you just copy/paste that 5 times and now every time the chorus plays it sounds perfect. Maybe the instrumental solo was perfect the third time, so let's use that one.<p>This also makes you have great appreciation for those bands that recorded music before the advent of modern multi-track recording software, and were somehow dedicated enough to get that one perfect take where everyone in the band did great and nobody made a mistake.
