What's you favorite song of The Beach Boys and will their music ever fade away?

I was listening to an oldies station and only caught the tailend of a Beach Boys song I had not heard before. Can you believe that? My pc help me to locate this song and I have played it over and over again. It’s DARLIN’, a great song of the 60s. Question: will the music of The Beach Boys ever fade away? They are as popular today as they were in the 60s. How can this be? And, what is your favorite song recorded by The Beach Boys?
