Music App Bug?

It does not happen everytime but I have noticed it a few times now

when listening to music if I change from portrait to landscape most the time in landscape it shows all the album covers that I have loaded,which I assume is the normal behaviour

once in a while it will show 1 album with the tracks from the album, the kicker is its not the same album or artist I am currently listening to that is displayed

anyone else experience this

 

thanks
