Yes, that's what I wanted to address and in the same way Steam address it with video games. You buy albums but you get the convenience of streaming services with no additional fees forever. Same as with Steam, I expected users to keep buying album regularity even if they didn't listen to them much. (cue seasonal sales etc...)
Mostly because the goal was to offer a premium experience targeted at the classical music enthusiast. UX was close to what you can see with Apple Classical or Idagio. On the business side, the model was really Steam and not any music store, seasonal sales included. Anyway, I only had a few month to try to raise some capital and I failed, so it's history now.
