What is everybody's opinion about the overall "mood" of the song?
To me, it's very difficult to define, and probably more complex in that aspect than other DT songs. As it happens with PT por example, it's difficult to just qualify the song as "heavy", "happy", "sad", triumphant, etc. I'd say "hopeful" or something like that, but there are lots of diverging elements in the song. The tone set by the introduction is completely different from that of the outro, and the piano and guitar solos are kinda enigmatic and do not try to convey emotion just for the sake of it, for example. The guitar is heavy but not overly agressive, like they were at the brink of exploding but decided to restrain themselves. I don't know, maybe I'm reading too much into the song.
