I love Shazam, it is the most amazing app! The only thing that I have to complain about is that every once in a while, it just won't work. It doesn't open or anything. When I press the Shazam icon, it seems as though it's going to open, but then quickly goes back to the home screen. Is this a result of an iphone update? Or is there something different I can do to prevent this from happening.
