I'm using the column titles in the csv file to find the various columns. The columns have moved a few times under different releases, so I search for the column titles rather than hardcoding their location.
You could replace "play_count" with whatever the csv file from jemplode uses as its column title (I haven't used jemplode). Or just hardcode "PlayCountCol = n" where n is the column number (not letter) that contains the playcount. The same thing may apply to other columns if they are also different under jemplode.
Ultimately, I hoped to generate a list of the most often played songs, like a top 100 most requested songs list. But, the play count doesn't seem to get written correctly to the csv file, so I'm not even using that column at this time.
