I am following the advice located at this link to manually change the playcounts in Banshee by altering the database: Manually set track listen count in Banshee?
But it is too time consuming to individually change the play counts for every track in a playlist. Can someone give me the line of code I need to update every track with a given value (ex. year=85) to a certain play count number (ex. play count= 5).
