Cole's questions are good, and if it's the case that Spotify's model is not the way to go as mentioned in the conclusion, here is a possibility:
Download parts @$00.69 per video, like a vending machine: revenue from a download goes directly to the people involved.
So, if monthly subscription is @6.90 that's 10 parts/videos that the user has access to for the remainder of their time on the platform: each month they'll get 10 more. Math, baby.
And again, it has to include snowboarding, surfing, and snowskating.
