@HoneyCandiez, well... "Indie" is sort for "independent", the "indie" scene is any non-Yamaha vocaloid or non-major label producer. So the majority of Vocaloid and the majority of its music, is "indie" by technological terms.

I think you mean "Antonym"? I'm not sure if that is the word. The CFM 6 or Big 8, plus maybe VY1, IA, Yukari are part of the "mainstream" vocaloids.
