For me i particulary fall in love with singers with unique tones (particularly female singers) some of my favourite are
Minnie - (g)i-dle -her voice sounds nearly mysterious and eerly a lot of the time
Rosé - Blackpink - i love her voice and i think she is an extremely important part of blackpink. I also didn't realise how big her vocal range was until she covered if i aint go you
Aran - Fifty Fifty - her voice is very mature and has a nearly 1950s sound to it. I doubt cupid would have been so successful if it wasn't for her and sio vocal performance
Yujin - IVE - she has a really nice rich tone that is really pleasing to the ear. Her tone kinda reminds me of one of the members of monsta x who voice is also very rich.
Thoughts?
