Right you are, Peke. I could have swore that I checked out the standard Toolbar when looking for the new button. Must have simply skipped over it by mistake. It being placed right next to the Edit Properties icon probably made my mind relate that icon to the Sync Tags function.
Anyway, I appears to function as expected. Makes it a lot easier to play the same track back to back without having to wait until it ends and then hitting the back button and accidently skipping past it. It's probably the biggest help for those who use the shuffle function since you could skip several hundreds of songs down in the playlist and thus the song that just played (that you want to play again) isn't sitting right there one slot above the song that would have normally played next.
Props for the great script, Peke.
