Are there any lossless codecs that can be used on the iPod? I've seen methods of converting things such as .flac and other lossless codecs into .aac or .mp3 to then sync onto the iPod, but is there any way to have an actual lossless codec played on the iPod (a good chunk of my songs are in .flac and I don't like having the quality reduced)? I don't think that it would destroy battery life that much on the Touch to have larger files since it's flash memory based and it wouldn't take up battery since there are no spinning parts, right? Thanks in advance.
