I'm not hating guys, don't take this as bait, just my honest thoughts
First of all This kind of music was so unexpected, it's very unusual in Kpop as well. But I'm glad he likes what's he's doing.
Personally, this type of music/song isn't my cup of tea and I don't find it listenable or enjoyable, It is kinda hard to digest, maybe if I try to listen it many times I'll like it. I actually like the music itself, it goes well with rap too, but overall the feel is different. Rap parts are catchy but the chorus is the least likeable to me and I wish it was different. Though I know it has it's audience and I'm sure they are there for him. I don't take this on the level of title track, because it's just a pre-release so I'm looking forward to the full album and main title.
anyways good luck j-hope, I always loved his dancing, I hope he includes smth in the upcoming album
