Recently I've been listening to some more vocaloid songs and haven't seen any of the songs that I started liking in this thread, so I thought I would update my list. I think I prefer the fandubs on niconico than the songs with the vocaloids singing, but that is beside the point.

Here are some of the songs I've taken a liking to:

サイハテ
Palette
ロミオとシンデレラ
＊ハロー、プラネット。
ワールズエンド・ダンスホール
白い雪のプリンセスは
