Almost all of the songs lol Sometimes they just get stuck in my head and I keep singing until I listen to them. But lately I've been singing a lot "Koi no Hajimari wa Diet", I don't know why, but I sing this many times a day without stopping, even after listening to the song. And since Playboy PV was released, I sing it a lot too

koe .clap.

although i just sing na na na na~ rather than the lyrics .sweat.

SCANDAL BABY love the lyrics and gets me pumped up

Harukaze, since I discovered SCANDAL with this song I can't stop singing it in my head .happy.

Harukaze and DOLL.

It's usually totally random, but lately it's been either Aitai (kind of a lucky one for me) or Namida no Regret (typically when on the piano).

Harukaze , switch , shunkan and koe ^_^

If I'm at karaoke, Shoujo S is usually involved preetty much without fail lol. But randomly, I really like to sing lines from ShoujoM around the house. XD
