From the developer:
mpck is a commandline version of the Checkmate MP3 Checker. It is a free program that checks MP3 files for errors. It scans MP3 files to see if the frames are where they are supposed to be, whether the frame headers are correct and whether the frame headers are consistent throughout the file. It reports some information on each file and an indication whether the file is good or bad.
