Bug Description

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.

Music: 2.4.1003

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.
