Tuesday Tunes Do you get it?

So Hello!Project has made another double sided single and this time both song are equally good! 

Very grown up, and I must say, this is the S/milage I know, fun and fast and quirky!

And on a side note, Morning Musume's last single outfit was red and black, Juice=Juice too and this is sort of red-pinkish and black, do you think℃-ute and Berryz Koubou's next single will have the same colour-theme? 

I think that the lyrics of both songs are quite good and I like the beat.
But if I should choose a favorite it would be the second one "Ii Yatsu".
