Adding background music to 1.7.10 in a resource pack

I have been looking around the net and so far have not found a working answer.
Most text is either for 1.6.x, 1.7.2 or 1.8 or for making custom discs.
None of that is applicable.

First off, I am running Minecraft 1.7.10, so all responses should be specific to that Minecraft version.
Second, I am not trying to create custom music discs for the Jukebox.
Third. I already have the music files I want to use in the correct format. ( .ogg ).

I am trying to create a resource pack that adds to, or replaces the Minecraft background music.

I have found numerous reference siting different path setups.

I have checked the .jar file for 1.7.10, and there is no music what-so-ever in there. So no help here.
