I'm trying to decide if I should use AAC 192 kbps or MP3 192 Kbps VBR Normal Stereo... I'm using a 4th Generation 20 GB iPod and 192 kbps seems to be the best quality to size ratio for me. I listen to a wide range of music but really will not sample and encode different genres / individual CD's using different bit rates and encoding types each time. I am looking for the best overall option. Experience and / or advice anyone? Jon.
