First we cannot replace our musical tastes favorites by other musical choices , especially for example in classical vocal music if we dont like it in general...
Second we must stay open heart and listen to some one dat that can open this closed door for us which is vocal classical music... No doing so this new vocal classical music will not change our basic tastes... They will only improve it by enlarging our scope and deepening our relation with our innate tastes choices...
Third we cannot learn how to listen to "sounds" which are annoying for us...But in all the vocal classical there is songs thar are in now way exagerately annoying... Miracles of naturalness exist... Miracles of expressions that transcend vocal classical to manifest the art of pure expression and not mere singing even beautifully...
I will give 2 examples...
If you dont cry listening that you need a heart...It is no more singing...Because she pray really, she dont merely sing...

MarIan anderson never studied too much formally and being black opera and lied singer goes up to the top of the world by his voice power alone ...
She can sing ANYTHING, jazz, spirituals, operas, lieds or Bach and be the best there is... It is my favorite singer.... I was shoked when i listened to her the first time... By the way as you i dont like vocal music so much... But there is exceptions... These are some of the exceptions...

Schutz was coming back from Italia...He combined styles and created for me his most astounding work, with a rythmic expressive power putting him beside Bach who admired him... This music is like a " drug" , it move us creatively by stimulating enthusiasm....
Close the door, listen and it will not change your taste... It will open your mind to voices from another realm...
I definitely recognize that I’m limited by my tastes -- as time goes on, I’m finding less and less music that I want to buy. As mentioned above, I’ve never enjoyed the sound of Classical Vocals. It’s not the music. It’s what I experience as an overall highly exaggerated, unnatural and off-putting quality of the sound.
It’s not clear to me how one could "learn to listen" to a sound that one finds inherently unpleasant/annoying. Care to expound further?
I don’t mean to "pick on" Classical singers but this just happens to be one of the genres most affected by the limiting aspects of my taste.
