"I've got the music, so deep inside"?

I heard this great song today. It has a sort of electronic feel to it.

I think the lyrics in it go something like, "I've got the music so deep inside" but I'm not positive. Google is not returning any good results, which is odd as I usually have no trouble in ID'ing a tune once I have an idea of lyrics.

The only clip I can find is this youtube video. Try to ignore the background noise, I think it's an exercise class (I did not record it!).
YouTube - What is the name of this song?

Any help you could give me would be most appreciated.
Thanks,
Tim.
