Symptom
When playing a music file that contains a resource fork, iPod plays a small section of a random song after the first song ends.
Solution
To work around this behavior, you can either re-encode your music files using iTunes, or you can try the following steps for each affected file:
1. Select the file in the Finder.
2. Choose Show Info (Mac OS X) or Get Info (Mac OS 9) from the File Menu.
3. Click the icon for the file in the Info window.
4. Press Delete on the keyboard, or type Command-X to cut the icon.
Additional information
Music data in files, including MP3 files, contain all the audio data within a part of the file called the "data fork." Some earlier MP3 encoder applications embedded custom icon data into MP3 files, to identify them with the application. In some cases, this causes iPod to continue reading past the end of the actual music data. You might hear a portion of another song, which is the data that happens to be adjacent on iPod's hard drive to the data from the first song.
