When you get right down to it, iTunes is a glorified database. It’s a list—a searchable, sortable list—but a very high-profile one with some stiff competition (at least in the Windows world, where iTunes is also popular). For these reasons, Apple has put a lot of effort into making iTunes rock-solid. Not a lot goes wrong in iTunes.
But when the planets don’t align your way, may this chapter be your guide to iTunes wholeness.
Upgrading to iTunes 4.6 or later is the most important step you can take. It cures a long list of glitches that were possible in 4.5 and earlier versions. For example:
You can’t listen to someone else’s shared music over the network if they have a big music library. (The “Loading” message appears, but the shared library never does appear.)
iTunes suddenly crashes when you try to listen to certain radio stations (those whose Web addresses don’t begin with http://).
You try to share music with a version of iTunes before 4.5 (and get a “not compatible with this version of iTunes” message).
In these cases and many others, just downloading the free update to iTunes 4.6 or later solves the problem.
