You could write a song about some kind of emotional problem you are having, but it would not be a good song, in my eyes, until it went through a period of sensitivity to a moment of clarity. Without that moment of clarity to contribute to the song, it's just complaining.
Joni MitchellI wrote 'Big Yellow Taxi' on my first trip to Hawaii. I took a taxi to the hotel and when I woke up the next morning, I threw back the curtains and saw these beautiful green mountains in the distance. Then, I looked down and there was a parking lot as far as the eye could see, and it broke my heart this blight on paradise. That's when I sat down and wrote the song.
Joni MitchellI had made all these rules for myself: I'm not writing social commentary, I'm not writing love songs.
