I'm going to start a new thread on this because I can't take it anymore and I don't want it tucked away as part of another thread:

Every 3rd time (or more), when pausing Spotify, the album artwork remains on my lock screen, and the play icon next to the battery icon in iOS's top bar. I have to force close the app when this happens. This is the only app this happens with, and it seems to be a total failure of coding, because it's been this way for the entire time I've been a premium subscriber.

If I don't notice that Spotify's jacks my lock screen like that (let's say, by forgetting how awful this app is coded and hitting the pause button on my remote), the phone gets extremely, extremely hot and the battery drains at a cartoonish rate until I force close the app.

There've been about 6-7 updates since I've first experienced this and it's still not fixed. I've moved from the 4S to the 5 in that time, reinstalled the app, restored my phone, and still, this happens.

Fix this already, or at least acknowledge the darn problem. This is awful.
