File structure vs ID3 tags
Starting with version 1.8.0, the API provides methods for accessing the media collection organized according to ID3 tags, rather than file structure.
For instance, browsing through the collection using ID3 tags should use the getArtists, getArtist and getAlbum methods. To browse using file structure you would use getIndexes and getMusicDirectory.
Correspondingly, there are two sets of methods for searching, starring and album lists. Refer to the method documentation for details.
