Cool, a vocaloid thread. Any nice song to recommend? I've got Just Be Friend, Sweetie x2, Paranoid doll, Episode 0, Kokoro and Innocence.
Hey welcome to the thread! And remember, resistance is futile

I assume you just being involved in Vocaloid fandom rite? If you ask me, the best bet for you is to go through the works of some reputable producers out there. Most of them differs in tuning style etc, but they surely great. I'd suggest the works of:
1) Ryo (Supercell)
One of the most legendary producer in Vocaloid fandom. Primarily using Hatsune Miku, and gain notable recognition for his works. Or if I were to put it into words, the producer who brings Vocaloid into mainstream status, at least among ACG community. And if Supercell rings a bell, well the group is the one responsible for Bakemonogatari ending, although sang by Nagi. He even responsible for Project DIVA 2 and Extend opening (Look Here Baby, Sekiranun Graffitti)
Notable songs: Melt, When First Love Ends, World Is Mine (Although IMHO quite overrated), Line, and basically every single song in his album, Supercell. Do try listen to it. Great for newcomers. Plus all the PD's OP above.
2) 40mP (40 meter P)
By far, my favourite producer due to his excellent tuning, orthodox melody as well as his rate of work (He keep producing excellent works after works). He used Hatsune Miku as well as Gumi, and his works, to put it simply, just pure awesomeness.
Notable song: Jenga, Time Machine (Collab with 164), Future Line (Collab with 164), Futariboshi, Life Size Note, and shietloads more. Try looking for his albums, Life Sized Note, Kotaeawase, and Ookina to Jibun no Sekai IIRC. All are masterpieces, trust me.
3) DECO*27
Heh, never gonna lie, he is the one who responsible for making me such a Mikutard. He used Hatsune Miku and Gumi, and his Gumi works is awesome enough that he basically sparks Gumi popularity among the fandom.
Notable songs: Ai Kotoba (Nobody shall ever hate this song. NO FARKING ONE), Mukashi Mukashi no Kyou no Boku, Mozaik Role, Coward Mont Blanc. Can't remember the names of his albums, as most of the album names comes from word play.
I'd include Wowaka's works too (Rolling Girl, World End Dancehall, Unhappy Refrain), Kz of Livetune (Yellow, Last Night Good Night, Packaged), OneRoom/ Jimmy Thumb-P (From Y to Y, Calc, Starduster, No Logic), Doriko (Romeo and Cinderella, Uta ni Katachi Ha Nai Keredo, basically all song from both his album Unformed and Romeo and Cinderella), and lots more.
Happy discovering. All that I listed probably appeal to most mainstream listener, and a lot of niches still unexplored (Vocaloud, Jazz, Trance etc). Try look around on which one that suits your taste
