I just saw the Motorola ad last night. I was in the other room, and when I heard it, I was like, "IT'S MIKA, IT'S MIKA!" My older brother had some of his friends over and they all were like, "uh, who's Mika?" Luckily, my brother knows of Mika so he explained.
Mostly at school, not very many people know of him without me telling them, lol. But I have heard a couple of people singing Grace Kelly and saying "what's the name of that song?" or "who sings that song?"
As far as radio stations, I have yet to hear Grace Kelly. The main radio station here is always a little behind on things however...it will probably be different after his album comes out.
I'm sorta used to liking bands and singers that no one has ever heard of, it kinda makes me feel good when they hit it big I can say I've been following them for awhile, lol.
