Both Shazam and SoundHound are briefly flashing a red title bar when I press the Home button to quit them. They weren't doing this before, at least not to the best of my recollection.

Did both apps' developers happen to code the exact same quitting action on their respective apps?

Or is it iOS that is doing this for some reason I'm unaware of?

I managed to snap screenshots of both events:
