rating other k-groups.solo, including SJ

Super Junior: A+++++++++++++++++++++++++++++ (until my + in the keyboard breaks off) : this is actually quoted by another fan/ friend
DBSK: Better than 2pm at least// but far in ranking from SJ// say, not my cup of tea
2pm: sorry, not my cup of tea
SNSD: don't love them nor hate them. older stuff is better.
Wondergirls: catchy songs, better than 'right above' group
Big Bang: Don't know them
Se7en: Grade: A (appreciate him as a solo artist)
G.O.D. (early 2000s): A+
f(x): recently appreciate them as a female group; they are very hip. Very different from other female groups I've seen. I appreciate Amber's uniqueness/ tomboyish appearances
2am: Don't know their songs
F.T. Island-Appreciate them as a rock group (grade: A)
Shinee: very cute boys younger than SJ. Very cute. I like Ring Ding Dong as well as Replay

2NE1: I like their spirit as a female group; kind of similar to f(x)
BEAST: don't know him/ them either (I don't know if it's solo, haha)
