Spotify randomly plays music and not in the task list when it does.

Currently sitting in a class having a lecture on social psychology and suddenly my phone starts playing Teddybears Sthlm - Cobrastyle by itself. It is a song I've listen to before and have on a playlist, but it wasn't on the last playlist I've listened to on my phone.

This was the last heard playlist on my phone: Various Artists - Tomorrowland 2012_02 

This is the tasklist while Cobrastyle was playing with the volume off: https://www.dropbox.com/s/76vlb3au9kwrcqd/Screenshot_2013-05-17-08-50-13.png, normally spotify is present in the task list when open or when I'm listening to music.

It happened a few days ago as well, where spotify started playing a song I didn't know or had heard before.

Phone is a LG Optimus 4G and NFC, WIFI and bluetooth are all off, with only 3G/4G active as a connection.

Anyony get any ideas?

That image only shows chrome as running. What tabs were open in it at the time? Could one of those have been responsible for music playing?
