I’m interested in selfhosting, if possible, an equivelant to last.fm – it would analyze the history of what I listen to, and provide me with recommendations, and listening history reports.
Aside, last.fm as a federated service would be quite interesting. It would be neat to add a federated social media aspect to it.
Its possible with anonymous data. But you do need other user’s data. So it would need to somehow be not just self-hostee but also federated. With lots of dsts from other servers
