Nevermind, lol, I realized I was just being stupid. If your reading this, sorry to have wasted your time.
It would appear if you go into your FILES and play the music from there it has that issue I described above. As it does not open up into the player's sort of "App" it just plays the music in a smaller flash sort of form. But if you go into your apps and play the music from there it works just fine.....
I find it interesting that they had designed the tablet to do such a thing, especially if you attempt to open the music with ANY OTHER APP it opens the app....not opens a smaller flash version.
Thanks for writing the solution.
I didn't know it was coded that way in Files. It's a very strange way to do it. Especially since it then leads to the problem you ran into.
Q: If you press and hold a music file for a few seconds - Do you get a menu with a 'Clear Launcher' option? If so, does it let you use that and then on tapping next time, does it give you option to open it using the Music Player App?
