You may want to reset the Plays counter column on a music file that keeps track of how many times you play a file in Apple iTunes. Here’s how:
If you wish to reset the play count for one song, simply right-click(Windows)/CTRL-click (Mac) the entry in iTunes, and select Reset Plays. Click on the dialog that appears.
You can also perform this action on multiple files by using the CTRL buttons to highlight more than one file, the right-click on one of them. Selecting Reset Plays then will reset them all.
For all music files, use Edit > Select All then right-click(Windows)/CTRL-click (Mac) and select Reset Plays.
