Gaining Ranks Quickly

Recently, it's been a topic of interest of mine to see how quickly you can get to the highest rank of Ouendan 2, assuming you go in the "story order" of all the songs. I've assumed a high S-rank would suffice for most of the songs.

Rank 1) Easy - Song 0
Rank 2) Easy - Song 3
Rank 3) Easy - Song 11
Rank 4) Easy - Song 16
At this point, Monkey Magic unlocks. Whenever a bonus stage is unlocked, we will go back to play it on all difficulties from easiest to hardest.
Rank 5) Normal - Song 6
Rank 6) Normal - Song 12
At this point, Glamorous Sky unlocks.
Rank 7) Normal - Song 15
Rank 8 ) Hard - Song 2
Rank 9) Hard - Song 5
At this point, Samurai Blue unlocks. Slightly out of order, I finished this bonus after reaching Rank 10.
Rank 10) Hard - Song 9
Rank 11) Normal - Bonus 3
At this point, the Hidden mode unlocks. This means it is time to replay the entire game from Easy - Song 1 on Hidden to attain maximum rank earlier. If you are wondering, approximately the earliest time you can unlock Hidden is playing Believe on Hard.
Rank 12) HIDDEN Hard - Song 10
As a quick note, at this point the cheerleader picture unlocks. At this point in the game, it would be assumed one has no idea the cheerleaders exist.
Final Rank) HIDDEN Hard - Song 19

Well guys, it's game over. It is actually possible to obtain the final rank without even touching Insane. There's a challenge to all you osu! masters. Now go and do something else.

And that's how it's going so far. Expect more updates later.

Interesting. I was going to do the same thing when I got my Acekard, but you beat me to the punch! Yeah, I'm too coward-like to erase the data on my real game. Looking forward to new updates!

It's going to be a while before I hit Rank 12 thanks to the tedium of playing all the Easy stages over again. I'm still alive though, so hold tight.

Meanwhile, I'll see how autoplay handles the situation of fast rank ups. Oh, and maybe after that, I could see how fast you can level up with SPINNER MODE!!!

EDIT: As some of you may know, Ouendan 2 autoplay is known for spinning impossibly fast, so I'm gonna follow the same path as Mr. Red, only with autoplay.

Rank 1: I'm so good, I got it before I started playing.
Rank 2: Easy - Song 3
Rank 3: Easy - Song 7
Rank 4: Easy - Song 12
Monkey Magic Unlocked
Aaaaand my emulator crashed and data was erased. I'll have to get back there so I can continue. Looking forward to the next update, Akai!

Okay, the experiment has reached its conclusion. Look back at the first post for the conclusive results!

Wait, is Song 0 the first song of the game? Or is it the tutorial?

I believe Song 0 would mean a new game.
