More than one iTunes for one computer.

Question

I have a brother and a sister, and we all have iPods, but only one computer. We have a windows XP so, several different accounts. I already have iTunes set up, but my brother and sister don't. Is it possible to have 3 separate iTunes for each of us? If so, how? And if not, what can I do?

Answer 1

There are basically two ways of using multiple iPods on a computer and these involve:
a) Sharing a single iTunes library and or user account.
b) Creating multiple user accounts and having separate libraries.
Sharing a Library and/or User Account
If you want to share the one library, you can set either or all of the iPods so that they only get updated with only certain playlists (you can update from more than one if you wish):
Loading songs onto iPod automatically - Windows
Choosing the update option "Sync Music - Selected playlists" allows you to create a playlist specifically for the iPod and drag the tracks you want into it. If you tire of the list and want to change it, you just add or remove the songs you don't want. The ones you take out out remain in the library to be used some other time if you choose. You can read more about playlists at these links:

Or you can choose to update any or all of the iPods manually and just drag whatever content you want to them: Managing content manually on iPod
Loading the iPod shuffle differs slightly but it can still be used with the others, for details have a look at this page:
Loading songs onto iPod shuffle - Windows
It's also possible to have multiple libraries in a single account. To create or access a second (or more) library, hold down the Option key (or Shift key in Windows) when launching iTunes 7. In the resulting dialogue you will get the option to create a new library or navigate to the other Library.
Note: You can only have one Library open at a time and iTunes will default to the last library opened if you don't use the keyboard command to choose one. This can prove tricky when using multiple iPods, if you don't use the keyboard command you can risk syncing to the wrong library:

Separate User Accounts
Another option is to create a separate User account for each person on your PC or Mac (which it appears you have already done). Different accounts by definition would give you completely separate libraries. Each account utilises the same iTunes program located in the Program Files folder but has it's own iTunes folder, Library and iTunes Music folder and you load it with CDs etc just as you did with your original one. The iPod can be set to update however the owner chooses, sync all, manual or sync specific playlists
