I have no idea how they differentiate between crossover (Previn's Korngold) and soundtrack (McNeely's Waxman) or classical (Shostakovich's Hamlet).

It's good. But not very good in the long term. I loved it when I got it, but hardly ever listen to it anymore. It has been criticized for being too slow (typical Previn conducting I guess), and lacking a choir in some tracks (cheap record label).
I do not know either the original tracks, nor the Gerhardt albums, so I do not really find it slow or lacking a choir. Thus for me the album is fairly satistying. It is well performed and well recorded (though in a more 'concert-hall' setting).
Is it worth getting? I think it is, but I'm not a Korngold fan so I'm not too picky when it comes to how his music is handled.
