OhMyGosh! I really couldn't answer these, I mean like I LOVE all Vocaloids song and of course I got a list of favorites! Common songs of vocaloid that I hear daily is, Acute (I really recommend this emotional song) sang by Luka, Miku and Kaito. Then, there's React (my fav too!) sang by the cute Kagamine twins and Miku.. I really think it's the sequel of Acute. I also listen to Reboot- a really sad masterpiece about friendship, Romeo and Cinderella- Miku, Hello How are you-Miku, Just be friends-Luka and a lot more.

   But to be honest, my first favorite is Innocent-Hatsune Miku and now I'm totally addicted to Remote Control- Kaito and Miku.

REMOTE CONTROL:
It's soooo funny XD cause it's about a remote that could control a person. MUST WATCH!
