My Question or Issue

I didn't realize that there was a "like" button for the lock screen until my most recent app update. 

The "like" button only shows up during Spotify created playlists, it doesn't show up when I am playing a playlist that I created or when I am playing a song that I searched through the search function.

Any help with this?  I am on the most up to date version of the software and have uninstalled and re-installed the app.

Thanks
