Walls Don't Talk is my favorite on the album. I love his lower register, it's a great groove (it is on my Drive Time playlist, which I created SOLELY for Minho's Call Back and Key's I Know...) and just fantastic. ETA: Also, I love this mature sound - this song feels Adult in a way Peaches didn't.
AND I would love a TaeKai collab. I know it's not likely because Fandom, but still...I'll take a tiktok short!
