Lowlander has suggested that MM will calculate "track length" based on a formula. Inevitably, that's not going to be 100% accurate (although, define "song length"! Is it when the last note disappears? What about all those records where the artists have deliberately left silence at the beginning or end of a track?).
So "corruption" is not the only possible explanation - calculating song length based on file size and bit rate is an estimate. Google "mp3 file length calculator" and there are various tools that will calculate size - you could try out some of those and see what happens.
I some files which did seem corrupted, or just where song length was dramatically wrongly calculated, but only very few, and my collection is 50,000+ tracks. Certainly nowhere near a 10% error rate - but then what would the expected error rate be?
