I’m with SOCAN, and as a member, I can see how much money you should get for placements on every Canadian networks.
According to the “Royalty calculator”, 1 minute of theme music on Discovery should give you $13.24, but that includes the publishing pie, so it’s $6.62 for the writer.
So if your team is actually 20 seconds, and you only own the writer’s share, then you would make $2.20 per airing. That equals to $1.73 in US money as of right now.
I also have access to the performance data, so I could tell you how many times and when the show aired if needed.
But yeah, sometimes they’re 1 quarter behind.
