I expected Is This Happiness to sound a bit Paradise-esque. Like Bel Air's little sister. Now Flipside could be an acoustic track, just like her her old material. IDK why, the title just gives me acoustic teas.
Will wait for the 16th track, of course, but as for now, I think I'll put ITH after G&R and let FK be the last track. Not that I'm as big fan of this song as you are, but IMO this is very good closing track: it's cheerful after all the sad songs and gives you a good mood.
