Eu am incercat utilitarul si merge de minune.

“If you have MP3’s that are skipping, sounding weird, or that a media player like iTunes won’t open, sometimes you just need to run them through an MP3 validator app to check and repair the files. A great free MP3 checker is called MP3 Scan+Repair, it’s got an easy drag and drop interface that will repair MP3’s quickly.

Repairing MP3 Files
Download the MP3 Validator here
Launch the app and then drag MP3 files into the interface for them to be automatically checked.
When an error is detected in an MP3 file, a little icon will appear next to the name in the app
To initiate the repair, click on the hammer icon to repair the file
Note that you might want to make a backup before repairing the MP3 since it does overwrite the original file.
The repaired MP3 will appear in the same location as the original corrupt MP3
The process is pretty quick and you can repair a bunch of songs at once, it fixed one of my stubborn MP3’s immediately and now it plays and opens fine with iTunes.”
