If you have a large CD collection and are not familiar with Escient, you are not living life to the fullest. I now have all (or at least most) of my CD's loaded into 3 Sony M333ES 400 disc changers, where they are all instantly accessable by artist, album, genre, or song title, and play in full CD quality, not some MP3 perceptual coding scheme. I can display the cover art and more info on my monitor, create playlists, burn CD to CD copies, rip to MP3, and more.
