Add music to your own library
What is the problem you are facing?
When I'm following a remote library, the owner can remove music from that library and it would stop being available for me.
I'd like to have an "import to my library button" for albums and songs, similar to the download button, which makes sure I'll still be able to listen to those tracks even if the other person decides to delete them.
What are the possible drawbacks or issues with the requested changes?
None, that I know.
