And not simply because you want to create something 'new' really but just because there's something obviously wrong in the initial recording of a song or album.

For example, my digital copy of 'Nights Out' by Metronomy always used to bug me because it didn't flow well. For example, there was a clear 'break' between 'Nights Out' and 'The End of You Too' even when I had gap-less playback on even though it was really clear the first song was supposed to flow seamlessly into the second track.

All I did was remove that gap just at the right place so it now does what I believe it's supposed to and it really works.

I have also downloaded songs and found them to have 'blips' in them. At first, I assumed it was a crap download and downloaded it again - and again - from a few more sources only to find the same minor problem. So in the end I edited it myself and did my best to remove it. A case in point is in the 'Intro' from Blessure Grave's 'Judged by Twelve, Carried by Six'.

Has anyone else experienced a 'fault' as they see it in an album's recording and taken steps to rectify it using some music production software? If so, what was the problem?
