Song of the Week

"Once in a Lifetime" - Talking Heads
One of the coolest songs I've ever heard. I love the music at the beginning, I love the guy's voice and the strange things he's saying ("you may find yourself behind the wheel of a large automobile"), the unison in the chorus, it just sounds great.
But some parts of it I just don't get. I think the main theme is that life moves so fast and so much happens that sometimes you want to ask yourself "how did I get here?"
But some of the lyrics like "water flowing underground" and "same as it ever was" confuse me.
This song has been in my head because it's in the trailer for the new Oliver Stone movie "W."
