Yes, I have a user on pixelfed.social. I like it, and use it daily.
It is kind of like Instagram, but in the fediverse and is open source.
A cool feature Pixelfed has is the ability to follow hashtags, so your home feed will be a mix between posts from the users you follow and the hashtags you follow.

I have Jellyfin installed on my homeserver, works great for listening to music in my opinion. I sometimes use Bandcamp to find and buy/download music, which I then upload to Jellyfin.
