this is what i did. i got a tape player, hooked a male to male audio cable into my powerbook, set the computer and garageband so that it would record from the line in port. in garageband open (im assuming you have garageband) up a new basic track, name it to whatever you want(uncle bobs mood altering mix or whatever) , make sure its recording from the line in, than press record and than play on you tape player and it should record from that.
