Creating this playlist

[purinkle]

Due to a recent iTunes upgrade, it has become more difficult to create the playlists that I desire.

I used to create playlists based upon the highest 'Play Count' in my library and each tracks individual 'Play Count'

For example, if the highest 'Play Count' is 128 then a track that has a 'Play Count' of 121 will feature in the playlist 7 times (128 - 121 = 7).

This way new tracks would be under heavy rotation from the offset and old tracks would still feature now and then.

Now, when I go to add tracks to the playlist, iTunes keeps asking me if I want to add duplicate tracks

Is there some way I can disable this message box or some sort of script/add-on that can help me create my playlist?

Many thanks
