Keep it focused on community facing artists, remixes, dj sets, etc.
From what I've seen they suffered most from lack of direction, weak leadership, and no real business plan from the beginning. It seems (correct me if I'm wrong) it started as a hobby project and got twisted into a SaaS model that didn't fit it's purpose or audience.
As far as monetization - why not have a Patreon-esque system of support specific content producers/artists? I don't think a blanket monthly subscription is really a good fit but personally I would pay 1-5$ / month for specific artists/content providers and follow only them.
