How many songs does the iTunes store have?

Answer 1

The number of files is limited by disk size and the file sizes. iTunes can stream from files up to 4GB. Basically, The larger your hard drive, the more songs you can store there. But iTunes can link to external hard drives and USB Flashdrives at the same time, so if you have external drives and a hub, there is no limit.

You can set up iTunes in its preferences to either copy songs into your iTunes library, which limits the library size to the size of your hard drive, or have iTunes link to files outside the physical iTunes library, which means you can connect as many drives as you can and link to as many songs as you want. USB chains can be very long, and there could be a problem with the USB setup if you change the locations of the drives, but as far as iTunes goes, it is probably limited by what can be indexed by the system, which is probably in the millions.
