pipepipe and rimusic is what i use. youtube in the browser is fine too, if you disable that “open in the youtube app” popup (firefox for android with ublock origin addon is what i use, although i have experienced some regressions with the ad-blocker not working after youtube updates something, but ublock is usually on top of it and fixes stuff quickly).
also syncthing, if you’d like to synchronize a directory to act like a shared folder and be identical on both devices

I think NixOS would stand to benefit a lot by taking inspiration from openSUSE’s YaST system configuration tool. I think that if NixOS had a well supported graphical interface for creating and managing the system config, it would become so much more accessible to a very wide range of users who never would have given it a try otherwise, which in turn would bring in tons of new users and developers who will want to improve nixpkgs, etc.
