Locked screen shows track name Recently my Galaxy S7 started to show last track's name when the phone is locked. Even if the music player is turned off. How do I turn it off?

Edit
Looks like track information comes from any app: music player, Spotify, YouTube, chrome. Whichever app plays music/video last - it leaves a name on my lock screen.
Settings > Notifications > Don't Show

Blocks VLC, FBReader TTS, etc for Android 6, so probably similar on a Samsung ROM.
