Now while I will mention -> iRip <- this doesn't mean you should not backup your iTunes before you do this.
I own an iPad2 ,iPhone 4S, iPod nano and an iPod 5th gen.. I'm finding it near impossible to get all the same music on each... I want to wipe the music off all of them except the iPad.. I want to wipe my toshiba laptop itunes library and replace it with the iPad library... And then sync the other 3 with the new library.. Can anyone tell me how to do this?? I've tried to sync the iPad with the laptop library but it tells me the iPad will be replaced with the laptop library.. I've deleted itunes and reinstalled it but the same thing happens... I don't want to lose my iPad music...???
