I can't name many ambient songs or bands off the back off my head, but I like ambient music that helps set and adjust the mood. The Warmth by Incubus is a good one. How well they play the instruments, combine with its rythem soothens the mood and comforts those who listen to the lyrics. To me, the non-instrument sounds playing the back sound like waves gliding amongst the ocean as whale dance and sang below. How the lyrics apply makes me think one of the whales are unable to attract the others and let his warming determination die out. But he should not give up, he shall continue to experience the warmth before its blown away.
