If we want to support wav file in Music app, there are things we need to change:

1. Gecko: Add *.wav to for music so that deviceStorage can return wav files.
2. Gaia: Modify metadata.js to let Music app be able to parse the metadata of wav file.
User Impact:
  User can't play WAVE file in SD Card from Music app but can play in the browser with audio tag.

  1. Gecko already support to play WAVE file.
  2. Add .wav into
  2. But gaia needs to implement metadata parsing or use audio.mozGetMetaData().
