Got confused, between K-ON and Vocaloid. Right now Im in love with Seishun Vibration by K-ON. Here you can download it here : MP3 SKULL . And Disappearance of Miku Hatsune in here MP3 SKULL by cosmo . Dont know which better because all of them is good. But if you like Vocaloid, you can download some of their album here http://vocaloiddownload.blogspot.com/ .
