Haha SMAP seems like a really common reason as to how people get into J-Pop lol. Kinki Kids are my FAVES right next to V6 and TOKIO^^ I actually subbed Aisareru Yori Aishitai but haven't posted it yet (I'll post it now since you said you like it) I absolutely LOVE that song as well, and you're totally right their songs are HELLA unskippable! I bought their 20th Anniversary album specifically because of that >.< They are total bakas, my favorite is Tsuyoshi and my best friend likes Koichi (though like you said, they're both ridiculously lovable and it's hard to stay faithful haha) I've just granted you access, I hope you enjoy my current and future content and I hope we can be friends!
Sankkyu~
