A few hours ago, トラボルタP (toraborutaP) uploaded a new song for Kagamine Rin, entitled “Congratulations”. I completely missed it when I was writing my previous post, but this is トラボルタP (torabutaP)’s present for Kagamine Rin and Len’s birthday. It was uploaded on 00:00 AM, by the way. The song itself is awesome. By that I meant, one of the best Kagamine Rin songs ever. I REALLY love it. It’s perfect as the Kagamine Rin and Len’s Birthday Song, kind of like “August Bride” for Hatsune Miku’s Birthday Song by OSTER project. I guess now I can conclude that トラボルタP (toraborutaP) is the best Kagamine Rin and Len producer. Enjoy the song, and once again, Happy Birthday Kagamine Rin and Len!
