Note: iTunes 4 no longer has this limitation. See <

A single iTunes 2 music library can hold 32 000 songs. To accommodate more songs, you can create additional music libraries. Follow these steps;
1. Locate the "iTunes Music Library (2)" file inside the iTunes folder (in Documents).
2. Create a folder called "Backup" and copy the iTunes Music Library (2) file to it. If you make a mistake or change your mind about creating multiple Music Library files, you can go back to using this backup file.
3. Create a folder called "Library 1" and copy the iTunes Music Library (2) file to it.
4. Create a folder called "Library 2" and copy the iTunes Music Library (2) file to it.
5. Repeat for each increment of 32 000 songs. For example, if you have more than 64 000 songs, make two Library folders, if you have more than 96 000 songs, make three Library folders, and so forth.
6. Open iTunes, add, delete, or change the songs in the Music Library for the first 32 000 songs.
7. Quit iTunes, copy "iTunes Music Library (2)" mentioned in step 1 into Library 1.
8. Open iTunes, add, delete, or change the songs in the Music Library for the next 32 000 songs.
9. Quit iTunes, copy "iTunes Music Library (2)" mentioned in step 1 into Library 2.
10. Repeat for each 32 000 increment of unique songs
To access each of the different Music Libraries, copy the respective "iTunes Music Library (2)" file to the iTunes folder (in Documents), replacing the "iTunes Music Library (2)" file that is there.
Important: If you accidentally move the file instead of copying it, make sure you move it back to the respective folder, or else you may have to redo some of the setup steps.
