Most certainly. Clouds (Both Sides Now) is a song that is about as good as one song can be. This may sound a bit of a paradox, but I feel the merits of this song tend to be overlooked because of the popularity of the author and success of the song. Or possibly because it is too indentfied with the time it was most popular? Sad for it really is a timeless song.

Wheh you're at an open stage pay as much attention to the bad performers as the good ones. You'll learn what NOT to do."
-- Fred Holstien--

That can be as easily applied to songwriting as anything else.

That is very true. Jeri's point was there is the difference between the quality of the song and our personal preferences. But I suppose if you learn what not to do, as a matter of personal preference, you will help develop your own style and the effect will be the same as learning from a poor performance or a bad song.
