since stray kids tend to be a rap and dance heavy group i feel like their vocals tend to be less talked about, which makes sense kinda cause changbin and han are two of the best kpop rappers. i am mainly talking about chan, seungmin and I.N as the strong vocalist as felix, lee know and and hyunjin are stronger dancers but can still all sing/ rap well but i wouldn't count them as vocal line.

my favourite vocalist in stray kids is seungmin as i find his voice to be very soothing, i enjoy his tone but bangchan demonstrated his vocal strength in Voices. the weakest of the three is I.N but from what he has shown so far is quite impressive considering his age and how the group only debuted in 2017 plus he is the youngest but i can see him becoming a strong vocalist as his career continues.

overall i think stray kids is actually quite a well rounded group especially for how recently they debuted , they may not be the strongest vocal line but they still should be talked about lol
