Music playing randomly out loud

[MT110]

Spotify has started playing music out loud randomly on my android phone. This is particularly when I use my phone's timer, watch a video on YouTube or watch videos on Snapchat. When I've finished watching any other videos spotify will pop up and start playing random music really loudly. It seems to have been since my android phone updated a few weeks ago? Have tried reinstalling the spotify app and restarting phone etc but no joy! Really need this problem fixed.
