This question concerns “windows media player, version 7.1”.(newest) I have about 1500 songs in my media library. From this collection of songs I have created 30 playlists. Every song on all 30 playlists is different. There are NO duplicates on anyof the playlists nor are there duplicates in the whole collection of playlists.(so there are about 540 songs inclusive in the playlists) When I started this project I would just review the prior playlists, individually, as I was beginning to compilethe newest playlist,make certain none of the new list was present on any prior list and proceed.Easy. Now that procedure becomes cumbersome. My question is: Is there an easier way to check all prior playlists, within the windows media player environment, to see if a song is already present there, other than going back to each playlist individually. When I first started, this took only seconds, no problem. Now as the collection expands this process is very time consuming. Any suggestions?
