I do understand the instant guess people has given to the fourth element of the image and I somewhat support it is a song by Waterflame as he has mentioned in a YouTube: "My lips are sealed", we are probably observing the creator of the song. I could be wrong as well.

On the other hand, FireFrost is an available song for free usage for the game and this does mean it is not locked (obviously) which leads to the Conclusion it is not an option for it.
