On your iPhone, download and install the "Remote" application at the iTunes App Store. It will allow you to remotely access your computer's iTunes library, which can hold a lot more than your iPhone or iPod Touch.
Step 2: Open iTunes
Open iTunes on your computer and your iPhone.
*Tip: Make sure your iPhone and computer are connected to the same Wi-Fi network by checking their IP addresses under General Settings.
Step 3: Get passcode
Launch Remote on your iPhone and tap "Add Library" in settings. Your screen will display a four-digit passcode.
Step 4: Enter passcode
Back in iTunes on your computer, select your iPhone under the "Device" tab. When prompted, enter the passcode.
*Tip: To access your library via the Remote app, iTunes must be open on your computer.
Step 5: Remotely control iTunes
From now on, Remote will automatically connect your iPhone or iPod touch to iTunes on your computer as long as they are both on the same Wi-Fi network. Search, play, and shuffle all the music and videos you have in your computer's library – from anywhere in your home.
