Mike Love is just an idiot. He's not an artist, he's a voice. Brian Wilson is an artist. In fact, he is a genius. Though much has been made of the Dylan influence on the Beatles, not near enough has been made of the Beach Boys/Brian Wilson influence. (Another example of the biased media - they have always focused on recognizing John's influences and not Paul's)
I think "Good Vibrations" and "Heroes and Villains" rank right up there with the best Beatles singles. The one thing Brian Wilson lacked, however, was staying power. He did release some incredible work in the late '60s/early '70s, and some of his solo work shows flashes of brilliance. He's just never been as consistant as Macca - which is why Macca wins out in my book. I mean, the man can do everything. (Great studio work, great live performances, etc.) But Brian Wilson does deserve more credit than he gets.
