I have my library plus a library my friend shares with me. I feel like when i would generate a radio or playlist it used to use songs from their library. This doesnt happen anymore. When i go to his library many of his songs dont have the radio button. The ones that do when i click play track radio i get an error like the screenshot i uploaded. ![Screenshot_20240108-200018](https://global.discourse-cdn.com/plex/original/4X/f/0/7/f076755f15b32946e8f2a8379c82d3f92e80157d.jpeg) ---

For some things it will, e.g. track radio, check your settings in Playback \> Radio. It sounds like your friend has incomplete sonic data. ---
