There is a way to change the start and ending times of songs in iTunes so that you can listen to the exact part of the track you’d like to here. While trimming the audio file itself is an option, changing the start or ending time is more convenient and doesn’t change the file. This is great for live recordings that may have talking before or after a song that you don’t want to hear every time you listen to the song.
1. Find the song that you want to change the start or ending time for in iTunes. Right click on the song. Click “Get Info.”
3. Check the “start” or “stop” box and indicate where you want the music to begin or end. Click okay and sync with your iPod/iPhone/iPad.
