OK, let me get several things clear---
First---I do not hate the Counting Crows, nor do I hate Vanessa Carlton. I love CC's early 90s stuff, and Be Not Nobody has its moments. In fact, when i found out it was Vanessa Carlton on the backup, i was astonished, because it was much worse than anything else i've ever heard her do.
Second--Joni Mitchell is my favorite musician ever
Third--Big Yellow Taxi is NOT one of Mitchell's best moments vocally, though it is a good song. But she did much better on many other tracks. While it is catchy, careless fun, I've never really understood why it was more popular than countless superior tracks from Blue, Court and Spark, or Ladies of the Canyon.
This is just awful. They changed the melody in the chorus to an unsingable, pseudo-country mess that doesn't match the beat and slowed the tempo in the last verse, rendering it needlessly maudlin where Mitchell's attitude was more appropriately(though still slightly bafflingly) wistful and "oh-screw-it" flippant. And they added those god-awful Vanessa Carlton background vocals. Let me reiterate, Vanessa Carlton was not bad at all on her album BE NOT NOBODY, in fact, if she performed here as well as she did on BNB, she would be the track's sole redeeming element. As it is, all this and more, especially the mindless, unoriginal production, make this the worst single of the year. At least, I hope it is, because I don't want to hear any worse.
