Lumia 830 music player won't recognize all songs on phone.

I copied all of my music from my PC to my SD card, and opened the music app. Now, about 10 hours later, it still hasn't recognized all of the music I added. I checked with my PC and all the music is there. I checked with the Windows phone Files app and all are there. I even downloaded a two third party music apps and they show all the music. When I play a missing song with the third party players, it shows on my original music app as playing and on the proper album, but when I navigate to that album, it's still missing.

Is there anyway to force the built in app to refresh so it can pull up the many songs missing from my library?

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
