How to Transfer iTunes Store purchases from iPod to Computer?

I want to play my iPod music and videos on computer, but I don't know how to do that, here is the problem, is it possiible to transfer iTunes Store purchases from iPod to computer, any easy way?

To make it simple, you can follow these steps:

Step 1. Connect your iPod to the computer. If your iPod is synced with another iTunes library, the following dialog may appear:

Step 2. Click the Transfer Purchases button. iTunes will begin copying any purchases made with any account that the computer is authorized for.

If when you connect your iPod you are not prompted by the dialog above, it could be that the option "Do not ask me again" was previously selected. After connecting your iPod to the computer and its icon appears in iTunes, you can choose Transfer Purchases from iPod from the File menu.

Or, you can Control-click your iPod in the iTunes Source list, then choose Transfer Purchases from the shortcut menu that appears.

Please note that this feature only works for items that were purchased on the iTunes Store. Any items imported from audio CDs or acquired from other sources will not copy from your iPod to the iTunes library.
