downloading some music at the moment and I can't drag/drop my music onto my iPhone in iTunes

anyone know what the deal is? I haven't had this problem before

What type of computer are you using? And do you have the latest Instalation of Itunes?, and have you tried dragging it into the Music department and then syncing only muic to the Ipod/Iphone? If this doesnt work please feel free to Pm me for more detailed help
