Is there an easy way to rip and store both highest quality (flac?) and compressed (mp3?) versions of albums? Some albums I have are for "hifi" listening, some are for the kids' mp3 players, some for both. I rip CDs in dbpoweramp, then in itunes make an mp3 conversion. But i then end up with the album in itunes showing 2 of each track. I guess i need two "libraries" - an mp3 one and a "hifi" one?
