there're a lot of songs that use support male vocals as either back vocals to enhance the female lead singing(e.g. https://youtu.be/MN_WgwEmRaw?si=y6PsJsTyQXn1jDx7&t=48, most of songs of the band "Lamp"), as a lead-in to the main vocal part(https://youtu.be/okoWZUQ-coc?si=r4rBlk2dyINaK8EG&t=162) or just as adlibs(shigure ui's recently-famed ロリ song or https://www.youtube.com/watch?v=nVq_Gua4wsQ).
i've been noticing the pattern where if songs like that do get picked for karaoke, those small enhances simply get omitted, since bringing in other twin just to make a few noises is... silly? unreasonable?
simply put, the title is a clickbait, the actual topic is about an alternate, more accessible way for neuro karaoke to have support vocals, doesn't have to be ved ai if it's hard to organize, but it seems like the most sound(and !!! funny) option to me as i've heard it being quite expressive and capable at holding a note for long(which is exactly what's needed from a back vocal)
the examples are there simply to show what i mean, i dont necessarily want neuro to sing these specific songs. im sure there're other pieces that use these tactics among the songs you like
