Why don some songs appear when viewing by Song Name, Artist, Album, or Genre?
In order for mOcean to make a proper categorization by the song name, album, artist or genre, the MP3 files must have the relevant ID3 tags filled in. You can do this in iTunes or almost any other MP3 player. Even if this information is missing, mOcean will still list your song by its file name in Card: view.
