Yes you can, using ur Apple ID and password.
If you mean the same iTunes account, then yes. My sister has the same account on iTunes on our home computer as well as her laptop. But if you buy some songs from the iTunes store from one of the computers and you want the new ones on your other computers, you'll have to sync those songs into the other computers' iTunes.
The Home Sharing feature in iTunes 9 will work with Macs or Windows and between Macs and Windows. Ensure that iTunes is running on all sharing computers and that you are logged into the same iTunes account on each computer.
This feature is called Home Sharing. You can access music saved on one iTunes computer from another. This will works as long as you have home sharing enabled on both computers, are logged into the same iTunes account, and are connected to the same Wi-Fi. This service is not iTunes Match-related and is free.
Use the same iTunes account on both computers. If not, you can use home sharing when connected to the same WiFi network to transfer the apps and data.
From my expireance yes. just open up itunes on both the computers and it should work
Home Sharing is a new feature (in iTunes 9) that allows the user to view files on authorized iTunes libraries on authorized computers and allows the user to transfer them to different computers. It can also automatically transfer purchases. www.apple.com/itunes
You click on the Advanced button and then go down to turn on home sharing (I suggest doing this on the computer that has all the music on it 1st). You have to put in your apple account information. If you want to turn home sharing on another computer, then just do the same thing. If you want it to share between two computers, then you have to turn on and put in your account information on both computers.
activate home sharing on both computers. make sure they are both connected to the same wifi and that itunes is open on both computers. u can import the songs from one library to the other
A home network setup with multiple computers requires a router to give the internet to all computers. After all computers are on line, they can be synced with a built in utility to expedite sharing of information.
If you have 'Home Sharing' you can sign in on your new computer with your itunes account and your computer would ask you if you would like to turn on home sharing and it will guide you through the steps from there.
To use an iTunes Gift Card to pay for your songs click on the Redeem link in the Quick Links box (top right) on the iTunes store home page.
The Home Sharing feature in iTunes lets you share your music library, or selected playlists, with other computers on your network so that they can listen to your music. It is not designed to move music around between computers.
