i think all of BP's voices are lovely and pretty damn great in their own terms
Rosé has that sweet, lovely voice that has plenty of range and when she hits those nights and falsetto, it's like your in eurphoria
Jennie isn't the strongest singer of all time, obviously, but she can carry/hold a note really damn well and hold it together. she has laot of untapped potential vocally but as long as she keeps getting lessons, her vocals are really gonna flourish as she, & the group, progresses.
Lisa has a good voice too, as heard in just bits of 'Whistle' (the way her voice rode over that beat in the beginning >>) and in PWF. i cna't wait to hear what she can do with it besides serve some epic rap bars
Jisoo has one of my favorite voices in the game right now. she's not quite up there with Rosé, but her voice is easily recognizable & you can tell it can effortlessly fit any genre/song she's on. when she stays in the low range but ascends to the high range, it's pretty damn solid. her tone alone is so interesting that i cant wait for her to use it so much more in the future as well.
