About the song comparisons.....
The songs are just, completely different, sure it may be the same note played fast, but unless youre deaf you can notice the different rhythm patterns, and other notes/powerchords put in. I should know, since I can play both songs.
I like b4mv, expecially their new album more, and theyre not emo fags >.<
Look for a list of emo bands... oh look b4mv aint there, THATS CAUSE THEYRE METALCORE DUMBASS...
Hope this cleared up something for you ^_^
But onto the flash... well, voices were crap, animation was basic if anything but i liked bahamut popping up, and I loved playing FFVI. A bit over-rated, IMO.
