I think Pet Sounds is overrated too but not only were they the best surf band, they're really the only one anyone needs that has vocals. There are some great instrumental surf songs by various artists. Obviously their use of the studio was hugely-influential which maybe is why they get hyped, although I think a lot of their biggest hits are great, and I'm already on record saying "God Only Knows" is the most beautiful pop song I think I've heard. Among popular American bands I'd probably argue the Beach Boys on the whole are actually underrated . . . but I'm from California, what does anyone expect me to say? :)
