Description Jason He 2006-03-04 11:11:19 UTC

The definition for application/x-mp3 is having a false possitive on multi-byte
plain text files (see attachment)

I think we should remove this uncommon pattern, which is the culprit of this FP:

  <match value="0xfff0" type="big16" offset="0" mask="0xfff0"/>


================================
  <mime-type type="audio/x-mp3">
    <comment>MP3 audio</comment>
    <magic priority="50">
      <match value="0xfffb" type="big32" offset="0"/>
      <match value="ID3" type="string" offset="0"/>
      <match value="0xfff0" type="big16" offset="0" mask="0xfff0"/>
    </magic>
    <glob pattern="*.mp3"/>
  </mime-type>

Looks like it was already removed.
