title: What am I doing wrong with SKAction playSoundFileNamed so it will play .wavs but not .mp3s?
body: <p>I've run into this numerous times now. Client send me some .mp3s to put in the project. When I try to play them using this code:</p>
  
  <pre><code>SKAction *play = [SKAction playSoundFileNamed:@"birds.mp3" waitForCompletion:NO];
          [self runAction:play];
  [self runAction:play];
  </code></pre>
  
  <p>The app gives me an exception and crashes on that line.</p>
  
  <p>I took the mp3 and I converted it to .wav (in Reaper), change the code to load that, and no problem, plays perfect. I thought maybe the original mp3 had some encoding trouble, so I open it in Reaper, re-export is as a new mp3, still crash.</p>
  
  <p>When it crashes, I look in the stack trace (I think I am using that right) and it shows this, which looks like it is having trouble with the ID3 maybe though? Reaper does encode mp3s using LAME, I don't know if it isn't compliant or something? Anyone run into this?</p>
