Why does the Samsung music app change my local MP3 files

[Android Central Question]

I have my MP3 file song name, artist, album and other tags just the way I want them. I have to keep reloading the files from my PC to my S5 every few weeks, because my phone app keeps changing the files, probably when the song is played, not sure.

Is there a player that will leave my files alone and just play them, as is ?
