ha-ha is a guilty pleasure. XD It's just so catchy.
Or something. I love the lines that make absolutely no sense. Like... "Go club get drink you stupid ****".
Oh, on a random note... about lines that make no sense... in Tanaka's PIERROT song, I've always wondered, when he does this speaking/yelling-ish part that sounds like, "I don't wanna be a DUCK, I'm a PIERROT," are the words really, "I don't wanna be a rock"? XD; I always imagine it being "I don't wanna be a duck". :S Just because it sounds so much like he's saying that.
I wish KAT-TUN would release an album full of just solo songs that have never been studio released. :S I'd be so happy if they did that.
