Exactly. Consider Tubular Bells, that has many mistakes, and even badly tuned guitars, Mike Oldfield admits this himself, but this is mainly to do with a lack of studio time, and having to make it quickly, but the point is, even with the errors, it's a classic album, when he re-made it in 2003 without mistakes, some fans didn't like it because it had lost some of it's soul. So, I agree, it's not what I worry about either.
