I don't have any signed kpop albums or photocards but I do have some signed cheki from visual kei bands (cheki is the equivalent of PCs for vkei bands)
BLACKPINK- but because their song formulas are SOOOO predictable
its like:
Jennie starts song
Lisa raps
Rose/Jisoo do the prechorus (starts with Jisoo ends w rose right before chorus or vice versa)
chorus
Jenlisa rap
Jisoo/Rose prechorus (who starts depends on who started it earlier in the song
chorus
bridge (jisoo & rose)
dance break
plus their long ass hiatuses- like I'm impatient (anyways no hate)
