and i will go in a different direction and say to use apple lossless. i just had to convert over 1000 cd's from flac to these. why? well sonically, there is no difference between flac and apple lossless formats. almost any music player on earth can handle apple lossless. but if you ever plan to use itunes, iphones, ipads, ipods, etc - anything with an apple logo on it (and who knows, if you don't now you might someday) it will make your life much, much easier if your music is in apple lossless/MP4.
