What are some of your best iTunes add-ins? [closed]

Solution 1:

Doug's Scripts is a fantastic collection of AppleScripts for iTunes that perform a whole array of functions. I've often made us of them to help detect duplicate songs and just generally keep my music library neat and tidy.

Solution 2:

When I edit my mp3 tags with external tools, then I use needledrop to force iTunes to refresh its internal database with updated tags content (by playing each file a few seconds).
