Don't worry!
I am not very knowledgable on this topic but I think I remember that
the problem with random is that is selects.. randomly.. Therefore,
even with weights it is not guaranteed that you will have a strict
rotation between your playlists..
Speaking of rotating, I think that this is the reason why David
introduced later the "rotate" operator:
toots@zulu /Volumes % liquidsoap -h rotate
Rotate between the sources.
(...)
* weights : [int] (default: [])
Weights of the children (padded with 1), defining for each child how
many tracks are played from it per round, if that many are actually
available.
Have you tried this operator?
