Please note that Musicnizer is distributed as 'try-before-you-buy', which means that everybody can download the program and test all its features for free. No registration of any kind is required for testing. We recommend to use this option to make sure that you do not purchase a pig in a poke.
Musicmeter is currently not supported, but I think we can add this site pretty soon.
Musicnizer depends on ID3 tags when scanning your files. If your files do not have correct ID3 tags, you can fix this with a program like mp3Tag Pro
As to the list of albums, please take into account that input may depend on the database that you use. For example, the format like "Tori Amos American doll posse" should be accepted fine by discogs, but will not be accepted by MusicBrainz (which is used by default). You will need to remove the Tori Amos part (i.e. only the name of the album should be entered).
