Hi, I do have overfly as one of my songs too
. Well the music app in the galaxy player will read the ID3 tag inside your MP3 file to get the info. It will not base itself from the file name. In this case, I think the title would be the Sword Art Online book thingy. Also with the galaxy player, there's no sync program in particular. It's drag and drop. But you can download a program that make itself like itunes, it's called doubletwist and you can download it here:
Hope this helps.
