What's the best setting for ripping songs, or does it just depend on your preferences? I just realized that I ripped a couple hundred songs all in ACC 128kbps. Is there a difference if I set the preferences to MP3 128kbps? I listened back and they sounded fine. Could this be a way to save space and possibly add more songs? I think I was in the neighborhood of around 600-700mb and I had ripped probably 7-8 full cd's.
