On the CD case has been stated that the album was originally recorded analog, say on a tape. This recording was also used for the CD edition. Thus, the sound quality is not the best, the sound is flat and quietly. One has to its credit, then the mid-80s has been the change of record on CD and it was not ready, digital record. Therefore, it often came to sonic losses on CD. Who owns the vinyl edition of Soundtrack "Who's That Girl", has been more than served even better, the record sounds more dynamic than the CD. I wonder why the album has not yet been remastered. After 2001, the first three albums of Madonna Warner were indeed sound restored, because you would have the same also with can make "Who's That Girl".
The soundtrack "Who's That Girl" is in contrast to the film cult. Not only Madonna fans will find on this album Fallen. Especially fans of the synth sounds of the '80s, the compilation is not to be missed. But you should rather resort to the vinyl edition, which is available in well-stocked record shops still to buy new or one hopes for a remastering by Warner Germany, but this is still undetermined. Just funny that this has already happened in Japan. There was "Who's That Girl" remastered in 2005. Until that happens here in Germany, it will probably already be a new music media ... So, if I have already a CD output must, then I advise rather to admittedly expensive Japan-Import.
