With iTunes, it doesn't matter whether I have Ludwig van Beethoven, Ludwig v. Beethoven or Beethoven in the Composer column, a search on "Beethoven" in composer will still find it.
Are you saying that with SqueezeBox that is not the case? I was sure that Sooloos behaved the same way, but perhaps that was a hasty assumption.
Sorry I'm confusing you and me with reference to a "search". If you search on Beethoven you do get everything (and more) - what I meant was I like to scroll through my albums (like looking along a shelf) and to do that I use album artist (or folder, which amounts to the same thing in SB world). If I do that on composer, I get out-of-place albums because of the surname/first name ambiguity.
