I've heard them all as well (there have been what, 5 or 6 songs released now) and I agree they led with the strongest songs by far.
The most recent batch hasn't grabbed me, but I can see them growing on me the way BBAJ did.
And also, like BBAJ, I get the sense that they will work much better in the context of the show than as stand alone songs.
....but the world goes 'round
