Ability to apply multiple filter criteria at once to album list

Thanks for this proposal.
But again, what if we want “aggressive metal” albums? or “relaxed electronic” albums?
We want to specify both genre and mood tags (and possibly more):

  • do we want to specify a list of well known tags so that the server knows what to parse?
  • do we want to just add a “tags” parameter which is an array of {type, value}?

Should be something very related to the Expose additional data for media - #6 by Tolriq proposal
