How to stop music apps from changing lockscreen I am not new to Android, but this is the first thing that has actually stumped me. I noticed my default music app (Xperia Z1ˢ BTW) and Spotify both change my lock screen to the album of whatever I'm listening to. Is there any way to turn this feature off easily? I know my way around android, but I don't know the coding language. This isn't really a problem, but a few album art covers are not exactly school appropriate.

update

I have checked the default music app settings, and there is no option to change for this issue either. I'm using Android 5.0.2, and the offensive album art is through Spotify. I also have checked my settings for this, there are no "music" options.
You can achieve this by blocking all notifications from the app. This will prevent Spotify from showing any notifications, including the album art on the lockscreen. The app will still work and play without issue.

Keep in mind this also prevents Spotify from showing the play controls on the lockscreen as well, so if you want to play/pause/next-track/previous-track, you will have to open your phone. I would suggest adding the Spotify widget to your home screen so you have quick access if you need to pause playback quickly.

Thankfully, you can still control the volume with the hardware volume buttons, even if the screen is off/locked, so if you quickly need to stop music you could at least turn the volume down quickly.

Below is quick tutorial. I'm running an older version of Android but you should still have the option to Block All notifications regardless. Your options will just look a little different from mine. Hopefully this works and is sufficient for your needs!
