I just thought of an addition to the spreadsheet that would be nice. A script that will auto sort them for you from most played down to least played. I have one setup in my sheet for this poker group I am in that keeps track of points earned each game. As soon as a new game is played and data is entered the script kicks in and will resort the leader board. Just makes it easier to see the tunes that have been played the most.
The only problem I would see is that you would need to tweak it so it only sorted certain rows and then you would not lose your grouping at the end.
