What type of music is suitable for current MM~ne?

MM is always a group which can have reaction with different types of music ~
Its not right to say that they are fixed in a certain style of songs.
For many people, the concerning part is that, within these few singles, or from the newest album. Most of the songs which 9 people sing together are sad in atmosphere. Is there really a reason behind all the sad themes?
I am not sure , but I think that maybe it is related to the current members.

Rokkies , which joined MM in 2003 with their cool/ darkish attitude. At that time,
Eri, her personality was shy. [ Secret, hidden side]
Sayumi, little cute devil image.[Evil + innocent / ones get hurt...hard to recover side]
& Reina, the yankii one. [Harsh, metal heart side]

Although they are now acting way different from before, their hidden personalities are still the same as they first joined. [ Its not things that time can change~]

I think that they can give out a special feeling when singing sad "theme" songs .

Then for Gokkies, only Risa and Ai chan left.
Ai chan is always good at singing touchie songs. From her "Yume Kara Samete", "Osaka Koi no Uta" and many more MM single, she is just fantastic with that .
Gakisan has a thick voice like Aichan, so she is good at sad ballad too.

7th and 8th gen can bring out a lot of different possibles. But since their role in current lineup in not as important as 5th + 6 th. [I Like them, they just need chance ]
Koharu with her Genki side / but looks sad and mature when off camera...
Mitsui , sunshine smile / always mention that she is lonely ?!
JunJun, looks happy, but sometime looks lonely [ !?] / her whole image really brings the "sad" PV into another level~
LinLin , happy all the time but with her thick voice , same situation as Gakisan ~

5th and 6th gens are now playing an important role in MM. As a result, I think that they will do better in songs which are touching.
