I better silently start re-downloading your entire library to internal storage, nevermind the fact that there is not nearly enough free space there, I'll just crash when it fills up."<p>"Oh, you rebooted your phone, and the SD card isn't initialized yet?

Must be because we haven't rammed it down your throat hard enough. Here, let's have them at the top of your home screen, and better yet, let's have some with sexually inappropriate imagery and titles. We know you don't want to see them, and we don't care."<p>I've experienced lots of incompetent software, and lots of malicious software in my time, but Spotify takes the cake for being both at the same time.
