I am a multi-instrumentalist as well, so I do undertand your points, Beauty/Broken, even if I may disagree in some of them. I did not say that the solo make the song, just specified what I think is a good solo. There's many songs without a solo part that are really awesome.
In that section of I.V. yes, they changed the rythm and tempo, but they still using a secuense of powerchord with thirds, if I'm not wrong. But yeah, it is indeed a very good part. Almost every Metal song is based on powerchords, so I realize that it's pointless to argue this. Again, I did not say that a super fast song is always a good song. Let me say that I love songs with creative changes of tempos and rythm, like Art of Life. In conclution, I really like I.V. and Jade, I just don't think their are hard, complex and technical.
I think this songs are like, Celebration, Joker, Miscast and Easy Fight Rambling. Not in style but about creative. These songs are quite different from their fast songs (wich I really like). They have more riffs variations and some of them are really really hard to play, at least to me.
What do you think about Born to be free?
