I don't mean that they can't sing, but their vocal tone. Apart from Ryujin who doesn't sing much, the other 4 have very similar vocal tones. Lia is obviously the strongest but she doesn't have the grunt that many other main vocals do which doesn't give enough distinction from the rest of Itzy. Chaeryeong and Yuna are quite similar and Yeji bridges the gap between them and Lia.
It just makes repeat listening to Itzy's songs harder. Most of their rivals have 2 or more members in each of their groups with distinctive voices that you can really tell apart.
Like all members in Blackpink and Aespa. Jihyo, Nayeon, Jeongyeon in Twice, Wendy, Seulgi, Joy in RV. Lily, Haewon, Sullyoon in NMixx. Yujin, Liz, Rei in Ive, Yuqi, Minnie, in Gidle. Chuu, Heejin, Jinsoul and Kim Lip in Loona.
Anyone else feel the same? Or do most people disagree?
