Solved! Volume consistency on mp3 downloads on Samsung J5 Pro

Jun 2, 2018
I have downloaded MP3 music files from numerous sources on the internet onto the micro SD card of my Samsung J5 Pro cell phone. When I subsequently play back music through my Bluetooth speaker, the volume is inconsistent between songs, some loud, some soft. Is there a way to tweak the android settings to get the same volume intensity throughout the complete playlist? Thanks for any advice.
