My Question or Issue

Ok, first of all, it's a pain to log a bug, I don't even know if this is the right place to do so. But, here goes. This morning, I was able to skip more than six songs (don't know how many, but more than six for sure), go back (I didn't try, but the button wasn't grayed out), and move from point to point in the songs. My plan is free, so I shouldn't be able to do that. I had ads, but the rest seemed like premium features.  Just the heads up. But, really, reporting this bug was an unnecessary journey.
