I couldn't possibly pick an all time favourite, but here's some that spring to mind.
"Why did God make me feel there is more to be answered? Maybe God cannot remedy our souls if he tried?" - Kamelot, "Farewell"
"No one surveys the whole. Focus on things so small. But, life's objective is to make it meaningful." - Epica, "Sensorium"
"Horrifying fecal demons/ Rising up out of the caverns below/ Dark robotic astral zombies/ Eating the peasants who live in Glasgow." - Gloryhammer, "The Siege of Dunkeld" (from Glasgow, I laugh every time)
"I've got this madman in my mind, this prolific designer. And he's working overtime, and he gets all wired up." - Poets of the Fall, "Drama for Life"
"'No reason to get excited.' the thief he kindly spoke, 'There are many here among us, who think that life is but a joke." - Jimi Hendrix, "All Along the Watchtower".
