Ok. They're just a rookie but, I dare to say that they is THE BEST K-POP GROUP EVER MADE. That shit is happen to this group! 100000000000000000% talents
You have to understand that there a thousands of Kpop Groups. Some are more populat than the others. From the girlgroups Blackpink is most definitely the most famous one. But that doesnt mean that they have the best music or style. In the end you will judge what group fits you style the most. Also there are different labels which each group is signed with. Depending on the label the groups tend to have different styles and videos and dances. Blackpink is under YG Entertainment and NMIXX is with JYP Entertainment. I would recommend you to check out more groups. Such as TWICE, ITZY, AESPA, GIDLE, IVE, Dreamcatcher, etc.
Nmixx's music style is called 'Mixpop'. It is an experimental genre of music where they mix different music styles in one song so that u will feel like there is more than one music in a single song. Nmixx debuted in 2022 with their debut mv 'O.O'. 'Dice' is their 1st comeback after debut. Just Fyi, please don't compare kpop groups like you compared Blackpink with Nmixx . It will only lead to fanwars and more hate towards these groups.
So I see a lot of people getting mad because you compared Nmixx to Blackpink, please understand that a lot of conflict between fan happens because they have a "competition" for their fav groups, but really, there is competition everywhere and it's true that it can be annoying to see people comparing x and y when they have almost nothing in common. So please understand that some are just tired of it, but definitely can't blame you for comparing them, you know nothing about kpop except Blackpink, it's new and it's the only thing you can compare to Nmixx. It's fine for now, you're gonna learn if it interests you and your gonna see how large and different Kpop is, just take your time!
