Need songs to make my vocaloid-hating boss not hate vocaloid ao much!!

Hi everyone!!! So, for context : im a teenager and i do volunteer work at my school's library, i once ended up showing my boss (AKA: the librarian, AKA: 30 year old very smart nacionalist modern lady who really hates AI and anime) a short recording of world is mine on a live concert and she was HORRIFIED. She absolutely hated it😭😭 she hated the concept of hatsune miku as a whole, hated the lyrics, hated the fact that it was a live concert with a huge crap load of people watching a hologram, yada yada yada. So, july's vacation is almost over, and im going to meet up with her again after a long time, so i want to redeem myself and show her a song that makes her not hate vocaloid so much!!

Some info : we are brazilian, and she doesnt speak english, so a song with portuguese subtitles available are very welcome. She absolutely DESPISES ai, so any synthV songs are out of question. Im not sure what her favorite music genre is, but definetly not anything too fast-paced or even slightly alternative like rock or hyperpop (songs like mozaik role, mesmerizer, Melt are all of question). I feel like she would enjoy slower and lighter songs, like tricolore airline, not anything too cutesy though She hated the high-pitched vocals from miku, so any songs with high-pitched tuning and voices are out of the list. Some arguments as to why vocaloid isnt degenarate anime music are very welcome too!! I wont be reading them out loud to her because tbh admitting to her i posted this is kinda embarrasing, but i'll try to convince her that vocaloid isnt complete trash!! And most importantly: the song needs to sound good for a NON-vocaloid listener!!! This might sound weird but many of us are so used to vocaloid songs that we end up forgetting how weird japanese robot music sounds to the avarage person, so keep this is mind!!

If you really read all that, then thanks!! Keep in mind that im doing all this for fun, and i dont mind her hating my lifelong icon at all! Vocaloid isnt for everyone after all, and if you think that this is a very "cringe" and weird thing to do, then keep in mind that she is around weird teenagers like me 90% of the time and is used to this kind of stuff😭😭 my school is full of vocaloid fans anyway
