Why? Because every Vocaloid Chorus Forum should have a favorite songs thread (plus birthday ideas HURRHURR |D)
My 2 favorite songs are:
1. Happy Synthesizer (Gumi & Luka) - Easypop
Pfft, we all should have seen this coming =w=)b
2. ARiA (Miku) [But I like lino/MARiA's covers better >w<] - Toku
Skip to like...:36 if you just want to hear the song
