[MuGen]

name two bands? Thats too much of an easy task... but i'll name four bands which their songs sound way different and unique from each album.

Incubus from Enjoy Incubus to A Crow Left of the Murder their sound has changed drastically.

Coheed and Cambria's vocal and guitar arrangements are just sick and are always innovative.

Dead Poetic is another great band that just reflects diversity. All their songs are so different which is why i can listen to the same album more than once.

Emery one of my favorite new comers is also great.

All these bands change their sounds and songs, and don't use the same arrangement and chords as Nickelback did with those two songs. I have a better word for cookiecutter, and that's Amatuer.
