I love the new KAT-TUN single. Every song is seriously amazing (except the Ueda Song which is ok, but not that amazing, imho). CHANGE UR WORLD and REMEMBER are probably my favourites, but the others are great. For GIRLS it's the first Junno solo effort I like. But maybe because it's not only Junno.
And wow, I kind of hear "I like to move it" from Reel 2 Real when I listen to it. If you don't know that song, it's also on the soundtrack of Madagascar. hehe....Anyway great single from KAT-TUN - 1000times better than GOING! and I dare to say even better than most of the last album.
