Plays random videos that have been cached

Its cool how you can find lots of songs and artists in an organized way instead of just searching, but it randomly starts playing videos that are cached, (even when Ive deleted them!) when I have the app open. Even if my iPod is locked! Its really weird and I cant find a way to make it stop doing this. I can temporarily pause it when I double click the home button when my iPod is locked, but it starts again a little after. I dont recommend it if you can run iOS 7 because there are better apps like this (that require iOS 7), but if you cant run iOS 7 (like me!) then this is probably your only (that I could find) free option that you can download videos on.
