Galaxy S5 notifications music pause

I believe an older version used to stop the pasing of music when you received a notification.

Unsure of how to keep continuous play on newer version. Using stock galaxy s5

That is usually a function of the music app.  If the music app detects audio focus was taken from a notification, it will decide whether or not to pause the music.  SoundAbout can't force the music app to force it to ignore notifications. It can send a request to the default music player to pause or to play, but that can be unpredictable as the default music player may not the the app you are expecting.
