How Can I Add Music to an iPad From a Computer?by Mario Calhoun
When connected to a laptop or desktop computer, the iPad will automatically sync with the iTunes library on your computer, or you can change the configuration settings for manual media synchronization. After the synchronization is complete, your music is stored in the iPod application on the iPad. In addition to adding music from your computer, you can also purchase music directly from the iTunes Store through the iTunes application on the iPad.
