I am wondering if there is an app out there on the market that can help you keep track of edits, changes, additions, deletions, corrections, etc. etc. to your music playlist. As I listen to my music I may occassionally find that a song is placed into an incorrect playlist, or I may hear a tune on occassion that I had long forgotten about and want to add it to my music library and playlists at a later time when I sync up my music. To date, I have used basic 'checklist' types of apps to keep track of my music / playlist notes and refer to this checklist when I do my syncs....this approach gets the job done, it just seems to be a little more cumbersome than what I would care for.
