I have a specific album on my Apple Mac in iTunes that needs to be copied to my iPod Touch. I have music on my iPod touch that was from another device (old PC), so I cannot sync the entire music library on iTunes (Apple Mac), as it does not have some of the music I have stored on my iPod, and will erase it.
If I manually select the album I need to transfer from iTunes to iPod, will that then erase everything on my iPod and replace it with the one synced album? Or will it just add the one album I need to my iPod, and leave all the other music on the iPod intact?
