Infographic increases by two for every track played.

[Gregory Opera]

When playing music using "Music", the infographic (on the Welcome Screen) increases the number of "tracks played today" by two for every one track played.

--

Reproduce:
- Copy some music to your Ubuntu mobile device, and start playback using Music.
- Check the number of "tracks played today" on the infographic at the start of each new song - If you cannot see "tracks played today", double-tap the infographic to change the data displayed and/or check your privacy settings (System Settings-->System-->Security & Privacy-->Stats on welcome screen).

Result:
- The infographic increases the number of "tracks played today" by two for every one track played.

Expectation:
- That the infographic increases by one for every one track played using Music.

Hi Gregory, thanks for filing this bug! Could you describe your methodology for reproducing this? The count of tracks played is incremented once a song has been playing for 10 seconds, so if you checks the first song immediately and then waited 10 seconds into the next song--you'd see it increment by 2.

I was referring to full songs... Play a song in full and watch the infographic change; play another song in full and watch the infographic change; etc.

All of the songs I am using are longer than ten seconds (usually 3 minutes or more).

In this scenario, the infographic is increasing by two for every one track played...

I can confirm the behaviour.

So the steps performed were the following:
1) New day - "no songs played" in usermetrics
2) Started music app
3) Played one song (file:///home/phablet/Music/Drones/02 [Drill Sergeant].flac) longer than 10seconds
4) Let a second song (file:///home/phablet/Music/Drones/03 Psycho.flac) start and stopped within 1 second
5) Noticed that usermetrics became "3 songs played"

This is an app log of what happened: http://pastebin.ubuntu.com/23988850/

As you can see at #3 (line 224) there is a "increment usermetrics" which is correct. However then you can see at #4 (lines 248 and 252) it increments the metrics as soon as the second track starts playing and then again when it is paused. I wonder if position takes a while to update when a new track appears, we should either fix that or be more intelligent.
