the new car i just bought has an ipod hook up and a USB spot. im thinking about getting a large jump/flash drive to put music on and keep that in my car. new egg has a 16gb drive for $19.99. how much music can i fit on that? i only have about 20 c.d.s here with me and thought it would be cool to put my whole collection on one drive and not have c.d.s all over the place. if the 16gb is too small, what should i look for? i do not want an ipod or mp3 player or anything like that.
