My Question or Issue

It is currently possible to like a song on radio even if the album of that song is already saved to my library. After that, I have that song saved twice, once as the album version, once as single song. That cannot be the wanted behavior.

As there is also no built-in possibility to check for duplicate saved songs and there also exists a maximum of 10000 songs per library, this needs to be fixed.
