BTS is also appearing at the festival so I hope this means J-Hope performs Spaghetti with LSF. Really wanna hear his rap live.

I don't think so BTS is busy promoting their new album. Performing an old song so close to the Grammy period when their main focus is on ARIRANG is highly unlikely 🤔.

u/Gentle-Giant23

Jeez, don't be a Debbie Downer. The festival is five months before the Grammy awards and well before voting begins. Preparing one song with Le Sserafim isn't going to consume a lot of his time.

My response was perfectly normal . Grammy nominations are in November and before that Grammy compaign happens which most artists do ,if only you tried to understand instead of calling me useless words. Assuming that BTS who have several Grammy nominations and are taking their time out in a very hectic and tightly packed tour schedule to compaign for the Grammy and for radio is a normal response. I would be negative if I said that lessarafim has none Grammy nominations but did I say ?. I only said that performing an year old solo song is unlikely when they are focusing on ARIRANG now and this show come close to Grammy time frame . What's difficult to think here or you just wanted to call me out despite not understanding anything yourself?

Yunjin is a member if the grammy academy if Im not mistaken so should perform spaghetti to get her vote…. I’m obviously kidding. If they were ever going to perform that song together, it would’ve been during LsF encore or a year end show or something. I doubt it will happen anytime soon.

u/Useful_Wasabi8679

Yeah ,my comment was not in a negative way for both groups . I know yunjin is a member of academy. I was trying to explain how it's unlikely for this song to be performed and how artists usually prefer their new releases during this time period and perform it..I doubt it too that they will perform it soon.
