Have any tracks hanging out in your library that were ripped from CD, and therefore include one song, a few minutes of silence, and then a bonus track afterward? Well, this tip—an oldie but a goodie—will show you how to split the two using nothing but iTunes.
Simply find out the time code for when the hidden song starts, make sure you have the track selected, go to File > Get Info or hit Command-I on the keyboard, go to the Options tab, and then set the Start Time to the start of the hidden track.
Hit OK, and then with the song still selected, go to Advanced > Create AAC Version, or select the same option by right-clicking on the track.
After a short conversion process, you’ll have two copies of the track, one of which is complete, and one of which contains only the hidden track.
