What is going on with the spotify app

[lumster49]

So i'm just listening to my songs on my phone just relaxing and wanted to check what song was playing now but i noticed  in my unlocked screen Its playing Enter Sandman by Metallica but thats not what it says it's still says playing whatever the last song was played. This happens every 6 songs or so and if i want it to work i have to shut off my phone and restart it again. So is this glitch going to be fixed or no
