KEXP Isn't bad. It's sad how many Alternative/ish stations are dying out though. of the non-corporate variety of course
My favorite station was WOXY/97X out of Cincinnati (yep, that same 97X Rainman made famous). They eventually went Internet only, moved to Austin Texas, then went defunct. it's quite sad really.
I got into listening to CD101 out of Columbus, Ohio which I was only able to listen to online, but they stopped streaming almost a year ago. (They are still on the air in Columbus as CD102.5, but I'm not in range of the station) who knows how much longer they will be around.
I got hooked on a station closer to home V 107.3 Cleveland but it only lasted 2 years, and reverted back to their smooth jazz format.
More recently I found out WFNX out of Boston sold their 101.7 license to the evil Clear Channel, but do plan on going internet only. Hope they have better luck than WOXY did.
Last year, Q101 Chicago ceased, but someone brought back something similar, Q87.7 .
I'll occasionally listen to 93.9 the river out of Windsor, Ontario. The signal gets in fairly well here near Cleveland
Back here in the Cleveland area, there's a new Adult Album Alternative station starting fairly soon. 87.7 "Clevelanders Rock". I really hope they can last a while.
