Database Commands
All the Database commands are available regardless of the power state, except for
Command 05, Play, which will return an error response if attempted during standby. The
groups, styles, and custom genres are grouped into system groups and user groups.
The system groups have system groupings such as the All group and Playlists groups.
The user groups contain the genres for your music and your custom genres that have
been created. Titles are returned listed in alphabetical order by title regardless of the
state of the user interface.
