KEXP 90.3 FM
Still the best station in town despite Paul Allen's grubby mitts. A few recommendations: Street Sounds (Sundays 6-8 pm) with DJ Kutfather remains the only FM source for underground hiphop in the city; Jack Straw Productions broadcasts live performances by local bands on The Live Room (Saturdays 8-9 pm), and experimental music on Sonarchy Radio (Saturdays 11 pm-midnight); and Greg Vandy's The Roadhouse (Wednesdays 6-9 pm) plays excellent "roots rock, blues, and Americana" by the likes of Fred Eaglesmith, Lucinda Williams, Blind Boys of Alabama, and Whiskeytown.
KBCS 91.3 FM
Bellevue Community College has international folk and American music covered better than any station in Seattle, with programs dedicated to reggae, African pop, and Hawaiian music (to name a few), plus hours of R&B, jazz, blues, and soul. Flipside Fifties (Saturdays 5-7 pm) is two hours of lesser-known R&B and rockabilly, followed by "the sounds that shaped soul music" with Bob Anthony on One Step Beyond (Saturdays 7-9 pm).

KISW 99.9 FM (Entercom)
A decade and a half late, but just in time for the coming years of snarling commuter hell, Howard Stern (weekdays 6-10 am) is the edgy morning show that the edgy morning show you're listening to has been ripping off. Poorly.

KYCW 1090 AM (Infinity Radio)
Classic country and western music, the sort that don't get played on FM no more: George Jones, Willie Nelson, Patsy Cline, George Strait, Waylon Jennings, Charley Pride, and Tammy Wynette, made all the more charming by having to wrap tin foil around your antenna to hear it. Legends of Country (Saturdays 9 am-noon) profiles one artist each week, along with influential country music from the '40s through the '70s.
KSRB 1150 AM (Sandusky Radio)
Devoted entirely to old soul, KSRB plays five hours of soul and R&B every night on the Soul Food Cafe (weeknights 9 pm-2 am), plus gospel from 8 am-5 pm on Sundays. The week is rounded out with an additional 136 hours of soul. Damn, that's a lot of soul.
