Hello i have two questions to ask about iTunes:
1) If i buy tons of songs via my Apple account on iTunes on 1 PC, will i be able to get them all in another pc with my acc if it burns, for exemple?

2) I have recently bought the new ipod shuffle and i passed many songs into it, but i am not able to delete them because their names appear in grey. Do i have to select the option: Mage manually, but if i do that, will it stop auto-sync?
