    # first digit must be 0 or 1), and the player seems to do the right
    # thing. Real DIDL items sent to a player also have a title and a
    # parent_id (usually the id of the relevant album), but they are not
    # necessary. The flow charts at http://musicpartners.sonos.com/node/421
    # and http://musicpartners.sonos.com/node/422 suggest that it is the job
    # of the player, not the controller, to call get_metadata with a track
    # id, so this might explain why no metadata is needed at this stage.

Hi Lawrence,

In the line 'didl_item_id = "0fffffff{0}".format(item_id)', do you know how to get the actual 8 (hex) digit prefix?

This is needed if one wishes to add, eg, a spotify playlist to sonos favorites. If one uses "0fffffff{0}".format(item_id)', then the spotify playlist will appear under sonos favorites, but it will be greyed out in the sonos app and cannot be queried or played.

I've been looking at the information available via MusicService('Spotify') and MusicService('Spotify').account and cannot find anything which correlates with the 8 (hex) digit prefix, so for the time being I seem to have reached a dead end.

The prefix appears in the sonos favorite DIDL-Lite once a spotify playlist has been successfully added by using the sonos app and I've confirmed that if one obtains the prefix that way and then uses it (instead of 0fffffff), then the spotify playlist will be added successfully to sonos favorites with full functionality.

However, that's not a viable way of obtaining the prefix if one is attempting to build an application that works independently of the sonos app.

Hope you can help!

Richard

@relevitt sorry for the delay, I've only just seen this. Unfortunately, I done know what the prefix means. I assume it encodes the music service or account I'd in some way, but like you I don't know how. Let me know if you find out!

thanks for the example, it served for me. i was trying to add a url from spotify to a playlist in sonos and your code served well !!
