DynamicPlaylist instances are created, but no songs generated (Python 2.7)

[LiYChristopher]

I'm having trouble getting the Dynamic Playlist object to work. I really want to be able to use a seed_catalog to generate the playlist, but any method to fetch songs e.g. get_lookahead_songs() returns None.

standard_playlist1 = playlist.Playlist(seed_catalog=u'CAZZOPK15261351B73')
print standard_playlist1

>> <Dynamic Playlist - 96d0aed056df4e64997a16c670eae817>

print standard_playlist1.get_lookahead_songs()

>> None

I have tried simple using an artist_id or artist argument, but it's not working.

On the other hand, the static playlist works great through any generation method (artist, artist_id or seed catalog). Based on the documentation and the existence of a deprecated dynamic playlist, is this still something of a work in progress?
