LG G3 :: Reset Stock Music Player

My situation is the base player was working fine for my needs. I had some music by the band "Kix". I added a song by a different band called "The Kix", and after uploading, all the "Kix" songs had been changed to "The Kix".

In trying to change the name of "Kix" back to the way it should be (no "The"), I have:

1) Copied all music from SD to Laptop.
2) Using Laptop, I went into the Properties of each song, updating and verifying all had the correct Title, Album Artist, Contributing Artist, and Genre. - including deleting the song from "The Kix" so there wouldn't be any confusion within the program.
3) Deleted the existing Music folder from the LG
4) After deleting the folder from the LG, I then copied the folder with updated information from my laptop back to the LG.

I expected that the new data would take, and that "Kix" would return, along with some other updates I had made. When I looked at the stock music player, I saw that most of the data changes (available through the Details option after a long press on the song) took, but for some reason "Kix" is still displaying as "The Kix".

I also noticed I couldn't use my old Playlist names, making me think that there are cookies/files (or the like) stored somewhere on the phone, and that data is still being accessed.

I then tried MediaMonkey, but that made things even worse when it imported the playlist and songs (duplicate songs, songs with wrong artist or album title, songs with lost data), and I'll be spending more time correcting their import errors than anything.
