First of all, the point of view of the "Odyssey" is told by Odysseus, while the "Siren Song" is told from the perspective of the sirens. Odysseus is trying to prevent the destruction of his crew. For instance," I stopped the ears of my comrades one by one." This suggests that the crew is trying to prevent the sirens from luring them towards death.
Next, the tone from both works of literature differs. In the "Odyssey", the tone is suspenseful, while in the "Siren Song", the tone is malicious. In the "Odyssey", the shipmates rely on Odysseus to prevent any harm to any crew.
