You may want to just manually manage your music. To do this, plug your iPad into iTunes and go to the "summary" tab. At the bottom, you'll see a box that states, "Manually manage music and videos." Once you've applied that, you can take any music in iTunes and easily drag it to your iPad. Now you can control what goes on your iPad without "syncing."
