I’ve uploaded a bare bones AppleScript that I’ve found useful over the past few weeks. The script, Increment Playcount, does what it says: it bumps the playcount of a track in iTunes by 1 and sets the Last Played date to the current date and time. It’s been helpful to me because many of my smart playlists rely on knowing if I’ve heard a track or not, but unfortunately sometimes my iPod doesn’t sync playcounts—and sometimes my iTunes library gets blown away, losing all playcount information.
To use the script, unzip it, drop the script in your Library/iTunes/Scripts folder, go to iTunes, select one or more tracks, then select Increment Playcount from the scripts menu.
