Tiny Light is a mediocre song (I know Grace says "it makes you think", but honestly, it's one of the most cliche messages out there); when in a live show, it has the potential to be great, but it really needs the energy to build it up, you just don't get that in a TV situation or a recording (especially with the "screaming"). Honestly, if you don't know GPN and you've just stumbled upon their performance on Ellen, it's understandable to think that they are not that great. 

And owllover, Ellen's audience spans so many boundaries that she is exactly the kind of exposure that they want. Everyone I know from my 13 year old sister to my 75 year old grandmother to my ex-boyfriend and most of my friends at college watch Ellen when they get the chance; she's major mass exposure.
