This sounds like a song that could be really addictive, damn its catchy, its got an upbeat mood to it though somewhat melancholic, could be a good dance song.
Wow, I’m 4 years late. Anyway, the non-katakana name of this song is 「愛想笑い」, meaning “fake smile”, or as a very direct translation, “loveless smile”. And if you listen closely to the tone of voice used with the program, and the pattern of the guitar and bass, it’s in a very dark and melancholic feeling. It’s meant to be seen as a dark, deep, emotional cry.
English lyrics from Vocaloid Lyrics Wiki: Laying lies upon lies; always just nodding my head, like a machine; ridding my heart of emotions, to maintain my own image- that’s how I keep up my good-girl act, day after day. Thus we put on a show of understanding each other, trying to guess what the other’s thinking. Aah, I’m forced to do the things I don’t want to do. I have no will on my own, no will, nothing. Aah, I’m forced to listen to the things I don’t want to hear. Day after day, it’s a love love love love loveless fake smile. I must paste a smile on my face, like that of a doll, to protect my own self, day after day. The jumble of my feelings, I must hold inside. No one notices my true self that I keep just below the surface. I’m forced to do the things I don’t want to do. There’s no meaning to my existence, no meaning, nothing. I’m forced to look at the things I don’t want to see. I get hurt; I hurt others-a love love love love loveless fake smile. In a world rife with liars like this, there’s no place, no place, no place for me to be. The heart is such a constrained thing, I don’t need it, don’t need it, don’t need it. It doesn’t hurt, it doesn’t hurt. I can’t feel any pain, can’t feel any pain. I’m just like a broken doll. See? See? Oh my, how strange. I can’t smile anymore…
