I've been working on ripping all my cds into itunes for a while now (powerbook+airport express=one beautiful wireless existence). at some point, the preferences got changed to import AIFFs rather than AACs. I dont really need AIFF quality (I'm keeping the cds) and it's taking up a LOT of hardrive space. is there any way to convert them into AACs in itunes without re-ripping? please, god, say yes.
