First some history. I have a rather extensive iTunes library and am looking for a third party application or a means through iTunes to more efficiently manage my database. Much of it is a mess as I imported them into iTunes 1 or 2 in Mac OS 9 when I started college years ago. This was done by me and two roommates over our home network for two or three weeks. Before iTunes had much of an auto label database. So each CD had to be labeled by hand and there was nothing like Wikipedia to find the proper genre of an artist so we guessed or made up genres. Genre Management: I have most of my music sorted down to sub-genres such as Rock - Doo Wop, Jazz - Bossa Nova, &c. This has been a work in progress for the last several months as I have over 28,000 songs. Anyways I find that on individual artists they will be in multiple genres, the worst offenders caused by soundtracks and compilations. So is there a program or iTunes function that will search out all artists that appear in multiple genres, display the tracks with genre info and allow me to place them all in one genre? Yes, I know many artists perform in more than one genre for those I just choose their most common genre. Advanced Duplicate Finding: First off I am well aware of the simple "Display Duplicates" function in iTunes. I am looking for a more robust duplicate detector to help clear the chaff. One great function would be ignoring duplicates between different albums. Take Led Zeppelin for example the songs in "BBC Sessions" and their regular studio albums are the same names. Since they are separate albums the duplicate function should ignore them. Yet always display duplicates from criteria I specify such as those with a blank album name. I would also like to have it ignore entire genres. Such as classical. As so many songs by a composer have the same name but are different parts of a composition like "Adagio", "Allegro", &c.
