They're gonna have to rename it ''I Am a Man of Only Occasional Sorrow.'' The surprise hit soundtrack to ''O Brother, Where Art Thou?'' had a huge night at this year's Country Music Association awards (held Nov. 7 in Nashville). The song ''I Am a Man of Constant Sorrow'' beat out Lonestar, Brooks & Dunn, Sara Evans, and Diamond Rio for single of the year, while ''Brother'' scored album of the year over Evans, Brooks & Dunn, Tim McGraw, and Alan Jackson. It's especially notable given the tune's scarcity on country radio; singles of the year are almost always big radio hits. ''I was dumbfounded,'' says Dan Tyminski (of Alison Krauss' Union Station), who moonlights in one-off band the Soggy Bottom Boys and sang ''Sorrow'' on the CD. ''I thought the album had a chance, but single of the year? I would've bet the farm against that one, just for lack of airplay. After the album went double platinum, it surprised me more people didn't say, 'Maybe we should play it now.' I think people kept waiting for it to go away. Oddly enough, it won't.''
