You are spot on, we don’t yet say enough that this is primarily an artist centred platform. We want this to be a place that artists share fans and get discovered by industry and playlisters so I think making this clear is key. Thanks for the input!
We are already collect genre data so will switch it on and have leaderboards when there is enough tracks of each genre. Just need to build up the pool of tracks and active artists first and prove the concept.
As I said before tastes are idiosyncratic so it makes no sense to have a single leaderboard. I would multi-tag each track by genre and language so users can rank by the subsets of tags that interest them. Ask musicians what other features they would value.
