Welcome to PEEL, Spacecowboy0080.
First, let me direct you to the FAQ
. You should read the whole thing. Don't worry, it doesn't take too long, and it's actually quite entertaining. Just read that, and you shouldn't get ANY backlash from other posters.
Also, although it's in the FAQ, I'll just say it here too...try not to double post.
Anyway, how do you know it was the exact same song? Did you have the song from that episode stuck in your head when you heard the commercial, or something like that? The holophoner songs aren't exactly the catchiest and most recognizable...you might have just been mistaken and thought they sounded the same.
I really have no idea, though.
