I recently bought an creative Zen as it was half the price of the ipod Nano and i'm looking for a simple mp3 compressor as it only has 4Gb of space. I have a lot of music but i'm not looking to lower the quality too much just squeeze a bit more music on there. Some of the songs i have are 9 or 10Mb and i think lowering that to 4 or 5 won't harm the quality too much, but i have no idea about it, i can re-convert the songs in itunes but that takes ages and is difficult to do for every song as some are at different compressions and are different sizes. Anyone got any ideas on software or know how much i could lower the size by without damaging the quality too much? Cheers.
