Incorrect total number of audio tracks

[LienLotus]

In the manifest file:
Total audio tracks are 8 tracks
But using mpd-parser, total audio tracks are 4 tracks

const mpdParser = require('mpd-parser');
mpdParser.parse(response.body)
audio_tracks_counter = Object.keys(parsedManifest.mediaGroups.AUDIO.audio).length;

Note: response.body is the content of the manifest file (in the attachment)
Env: Ubuntu 18.04, mpd-parser version 0.10.1

Closing this in favor of #77 because they are duplicates. We're going to try and look at this soon because it's definitely an important thing to get right.
