World is Mine - I could understand why you like this one. Nice guy voices. xD
Just Be Friends - Chorus and some other portions sound really professional. :3
Gemini - It's good in its own right. Can't say much because I'm not a big fan of the song itself. xP
Magnet - ...Yeah, guys. <3 Some parts are off, but that can't be helped when you so many people singing in one song.
I haven't been keeping up with nico chorus, but I do have some personal. I'm pretty sure you have seen them since they tend to be on the front page.
Cremation Melody Sound so natural here.
Meltdown Beautiful unique voices, and combinations. The song doesn't flow well at times. But hey, 12 real singers plus Rin. xD
Spiral Labyrinth Cuz I love the song? Beautiful voices here for the song, but the males are overpowered by females and they also sound out of place sometimes.
Dear Love the song, love the voices. <3
Solo Song of Thousand Years Pffffftt- Youtube deleted my favorite chorus version of this song. T-T
Solo Song of Thousand Years In case you prefer the softer version. ... ... -smirks-
