Very subjective but interesting thread. Based on ratings you would have to say KISW, KPLZ and KIRO qualify as the "great" radio stations in Seattle. KISW has a very strong, local afternoon and morning show that targets men and is number one both 25-54 men. 18-34 men and 25-54 adults. KPLZ has a very strong morning show and office listening image that targets women with local talent in mornings, mid-days and afternoons. It is number one 25-54 women, 18-34 women and 2nd or 3rd in 25-54 adults. KIRO-FM has become the top news and talk station in Seattle over the last year and usually finishes in the top three 25-54 adults and is very strong in mornings and afternoons. All three stations have live local talent and deliver their target demographics.
In years gone by KMPS, KZOK and KMTT would have been in this category, but all have fallen on hard times. Bob Rivers deserves mention, but the rest of KJR-FM is voicetracked for the most part and programmed by CC generic. KEXP is certainly the most unique, but great radio is probably a bit of a stretch.
