The true cd box set has a catalog number of VIZL-64. The one I purchased turned out to be from Alion, catalog number ALCA-8032/5. Some manufacturing flaws in the cd led me to do some looking into this.This box set, like much of Cowboy Bebop, has been out of print for some time now, and the existing box sets are somewhat of a collectors item, so beware of low priced items.The set I recieved has trouble being read by most of the cd and dvd drives I have, 'fortunately' one external drive can read them. I'd advise some digging around to be sure you're actually getting a box set from Victor Entertainment and not a bootleg if you are sensitive to such things.I've liked the music of Cowboy Bebop since I saw my first episode, and I saw this as a convenient way to get a fair portion of the soundtracks. The bootlegged versions of this product may not live up to your expectations of quality. Cowboy Bebop gets 5 stars. Bootlegs, well, can't go below 1, would if I could.
