iTunes duplicates

I would appreciate an answer to this question too. I dont know why but it seems that all my songs have been duplicated. Is there a way to simply erase all the duplicates at once instead of manually selecting each one? Is there any possibilities of having this added to a future version of itunes?

I've used TidyUp! and Dupin and know there are more programs to find dups - hope these help.

[these are, as far as I know, Mac programs but you might look into them and make sure - I'm sure there are Windows programs too]

Yes, I need to know, too. I have uninstalled iTunes 2x and installed 3x (along w/quicktime, etc.) and still the duplicates are there. With my dupes, one copy says "the original could not be found" and there's an ⚠ mark in the first column beside the dead copy. It's driving me nuts because I have huge number of tunes and don't have a week to delete every. single. dupe. If I could light up all the ⚠ marks in the first column and select/delete them that would be ideal.

Is it because I used Windoze Media Player? And do I have to delete the library from that program? Boy, what a PITA this is becoming...
