You can upload mp3s on deezer (website, but once you’re uploaded them you can Listen to them and download them in the app). So if there’s something particular that’s missing and you have a mp3, you can add it. I’ve personally never had problems to find things on deezer, but I’ve been using it a lot and it definitely shaped my taste.

I agree, if I subscribe to a community that has 2 posts a week, I wanna see those posts, eben if they have no comments. I wonder if a lemmy equivalent to a multireddit could also help? In a multireddit you could group communities into one separate feed (like just create a multireddit “cats” and add all cat related subreddits to this multireddit, and then you could see all cat related content within one feed.

Its not as good a solution as to have the algorithm push it, but maybe there’s a lemmy functionality I’m unaware of that could already emulate this process.
