I believe its the maximum number of songs your hdd can hold. I have never heard of a limit in iTunes. Of course, as always, I may be wrong.
 
There used to be a cap of 24,000 songs awhile back (before iTMS existed), but I think that was lifted. I'm aware of people with over 25,000 songs, and rumors of people with 50,000+.

You're likely just limited by your storage capacity.

Edit: This site contains a post by a user who ran into a ceiling at 32,000...but that was over three years ago...I'd bet the ceiling's been raised, if not eliminated by now. MacRumors article on this.

Edit #2: Apple support document showing how to get around the 32,000 limit in iTunes. It specifically mentions that iTunes 4 no longer has this limitation.
 
There was a limit (32.000 I think, but might be wrong) in early versions of iTunes, but that has been fixed... if there's still a limit I guess it's purely academic... ;)

Edit: Slow and partially wrong... d**n that distracting TV... ;)

BTW, why not upgrade to the newest version of iTunes? I've been using 6.0.4 for a while now...

Yup my research concures.

iTunes 2 music libraries are limited to 32 000 songs. You can overcome this limitation by creating multiple libraries.

Note: iTunes 4 no longer has this limitation.
From this I take it that iTunes 6 either has no limit or such a crazy high number that no one in their right mind will ever reach it! (...yet!) I'm guessing there still is a limit somewhere though, just very high. So sorry, no exact number!
 
If i even become very rich i will buy as many songs from iTMS until it tells me the max has been hit


I would think that the limit would be over how much stuff they sell in iTMS
 
yeah, and even in one of the threads here 'who has the largest itunes library' someone has over 150,000. which, I don't know why you would want to find britney spears through all that clutter, but ... whatev...:p

I have a friend who has over 81,000 Tracks in iTunes, and I saw a screenshot of someone's library with 120,000 tracks.
120,000 tracks! Wow do they work for a radio station or something? I didn't know that you could listen to that many tracks!:eek:
