I've listened to it 3, maybe 4 times. Will probably give it another play or two before the album comes out. Enough to have it sink in and grow, but not enough for me to be sick of it.
Then again, I have a feeling that when the album comes out, I (and many of the rest of us) will be overplaying other songs so much that OTBOA will sound fresh by the time we get back to it, haha.
