Any Hatsune Miku Project Diva players?

I love the project diva games. i've played almost all of them. I probably have over 200 hours combined on all of them. Some of my favorite songs are slump, sadistic music factory, gothic and loneliness, holy star, high school days, ill miku miku you, popipo, hello planet, ageage again, 39 music, rin chan now, CLOVER CLUB, close and open demons and the dead, mmorpg addicts anthem, happiness and peace of mind committee, tokyo teddy bear, look this way baby, just to name a few LMAO. I mostly play on hard and sometimes extreme. 

Tell me your fav songs and what difficulty you usually play on. Also which project diva is your favorite? I play mega mix on steam the most but I honestly think F2nd is my favorite. I have almost 90 hours on it.
