Why is there a song playing without any apps opened?

[Android Central Question]

I was chatting in facebook messenger and suddenly music started playing from unknown source, I tried playing music from spotify and stoping it hoping that the sound wont stop but it only overlayed on the song without stopping. I don't have any song saved on my phone and I am only using spotify. This happened several times already and all I did was to restart the phone, but I want to know more about this for it to never happen again. Thanks
