im VERY picky on wat gets put on my ipod, or anything in general i download wen it cums to music, it has to be near perfect quality quality or bust!
all my music on my ipod sounds just as good or better the cd's.....
i go as far as listening to them on my head phones and compare which file is better, and listen for any errors.... i increase the volume level on the ipod, n i have my ipod tuned right with my reciever in the truck, so no garbage gets fed to my speakers
and of course the convience the ipod has over any cd is of not having to flip thru track on an mp3 cd...
so for me ipod>cd's
