Collections are a way to organize and curate music, artists, and releases on Subvert. Think of them as flexible, named lists that you can use however makes sense to you - a wishlist of music you want to buy, a mood-based playlist, a curated selection with written context, or just a way to keep track of artists you love.
Any signed-in user can create collections. You don't need to be a co-op member.
Collections can be kept private for your own use, or made public and shared with others. Public collections appear on your profile and can be shared via a direct link.
