Thanks Deepblue, I`ve been mucking around with loads of trial version mp3 fixers/surgeons. None of them seem to work or even recognise popular formats.So desperate for one particular rare song,tried dissecting & reassembling a version using creative wave studio- Didn’t work but the mess would have made Frankenstein proud.

I`ll gladly try your advice,give it a whirl. Doubt it could help with files that are already full of errors like cracks,pops `n`skips though (unfortunately).

Must be super fussy or something
