The main reason we don’t see a lot innovation in this space from the streaming services, is that using the music inside an interactive experience such as a game requires a different license.

It would be fairly simple to make a tap/swipe/press game with a similar experience to rock-band, automatically for all music on a service. But having looked into this, together with a few major music services, the license cost made it almost impossible in practice.
