For whatever reason, I kind of stayed away from Luka's music when it comes to all the Vocaloids. I like her sound, but all the songs I tried listening to I didn't care for. (I do really like Tower, though.)
Then someone posted the following two and I love them to death.
And then I stumbled onto this third one. . .
I especially love the video for Secret. (Second video) So awesome~ Will make icons in the near future.
