Subject: Check the return code from each call to mp3info(), as it might return
 true to indicate a bad mp3 file.

TODO: when having a dir full of zero-byte mp3 files and pressing play on
one using the simulator, this'll go crazy.

TO CHECK: I haven't checked how the live target code behaves on this.
