Should i become an Icon?

after reading a couple reviews i'm stuck on whether or not i should get Def Jam ICon.

How long is it?

How many songs in the soundtrack?

Is the online mode fun?

For a casual gamer when it comes ot fighting games, is it worth the purchase?

mkay thanks, i really liked the whole concept of the second game but i though the story was kinda weak.

ah i'll probably buy it anyway.
