Spoiler: It's been a long debate since her days on YT, but Nano-san is indeed a girl. She should totally participate in one of those... genderbending mindblowing CDs. I like reading the comments on her videos that spark the debate of people guessing the gender, especially with tags like 「これは男ナノ」 made me www~ for days. XD

...Yay for Smiling covers... because the world always needs more smiles. :D
And Green Straight by MAGG & LOLOW because those 2 are drop dead sexy & have wonderful harmonies, despite the slightly overdone adlibs. /shot

Thanks for the write-up! :]
