The idea for OpenStage was mainly brought up to improve our promotional material. We had very inconsistent representations of Nightingale. OpenStage would unify Nightingale's appearance across all official screenshots.
The idea to recommend music in a media player seems logic. Every player does that, some even come with pre-bundled music. OpenStage is not pre-bundled music but a decent recommendation to the user. We hope to have a variety of genres to present to our users, so everybody will discover something they like.
