I am know buying/downloading music in WAV/FLAC as this I've been told is the highest quality and best for listening on a good system/DJing. However when using itunes and moving music to my ipod, I need a version in mp3 as well. So, in my itunes I would have each song twice (once in WAV, once in mp3 for ipod), this is pretty messy. Is there anyway around this?
