"Big Yellow Taxi" and "Field Below"

Both of the songs "Big Yellow Taxi" and "Field Below" are very sad and depressing when you read though them. They talk about sadness and missing something, but if you listen to the actually song and not just the lyrics, it completely changes how you feel when you hear it. "Field Below" is a slow song with rain in the background and a sad person singing it, and that is mainly what you would expect. But when you listen to "Big Yellow Taxi", it is completely different from what you would expect. The singer sings the song really fast and upbeat, and almost sounds happy. Instead of being sad when you hear it, it makes you think that the person has moved on and is no longer sad about it.
