Lockscreen with album background, but no widget

[Nayibmc]

A few days ago I noticed that if I'm not on the main "Now Playing screen" (I don't know what do you call it) when I lock my phone, when unlocking it, there's no widget on the lockscreen. It used to always be there, regardless of where I was when I locked the screen.
I'm on Marshmallow, Z5

I literally just noticed this before finding the thread.
