How do I turn off album cover art on my lockscreen??

I can't stand that when I am playing my music on a train or bus that when I go to unlock my phone the album cover art shows up all over my phone screen like so.

It's annoying. What if I am listening to Backstreet Boys and I happen to go for the unlock while sitting next to some beautiful girl I might ask on a date. Now I have a big picture of the Backstreet Boys on my phone screen and bam! she automatically judges me laughs on the inside and now I have ZERO chance of landing that date before she could even get a chance to know me. Not that I care what people think, but it could be a thing, you know? Anyone have any fixes for this?
