Can't speak for anyone else but.......If I can hear it, I'll try my best to cop it. I tend to pick up the little things like that. Many folks don't put that extra time into their listening to songs. Not only do I listen to songs, I listen to them all day long for weeks and even then some. I'm a hard worker when it comes to learning songs. I don't play around! That doesn't mean I'll always play it when I'm playing live.Frankly, I seriously doubt those in the note-for-note camp are as accurate as they say they are. You know, that ghost note in the 54th bar that's not exactly like the other third bars when the "B" part comes back around again. Or the 32nd & 48th bar that tie the eighth notes as opposed to playing them like the rest of the tune. As they say on Monday Night Football, C'mon man.
But that's just me!
