When converting some 1500 flac files to mp3 (my car won't play flac) it seems that a number (2 found so far) seem to have been corrupted in that part of 1 file has been included into another. For example the Blue Jays track "Nights Winters Years" when played as mp3 has parts of a Rolling Stones Hot Rocks track in it.
The tracks are fine as flac and only corrupted after the Batch Conversion. Unfortunately the mp3 is too big to attach (6.81MB).
