I often listen to Live365 while at work. So, I thought it might be helpful to share some links to stations that do good stuff, and perhaps also have a Seattle connection.
D23 Powerpop Plus - out of Seattle, and presumably named after The Posies tune "Dear 23." This is always a good listen. It doesn't seem to get updated very often in recent times (most recent update was November, 2006). But, it's full of great tunes of the powerpop variety.
Shake Some Action radio - out of Seattle and programmed by James Hall of Shake Some Action and The Jeunes. James has dipped into his collection and put together some great hours of music. I'm not sure how long it goes before repeating. But, what's here rocks.
Power Pop Of The Gods - out of Seattle. I haven't listened much here. I just found this one today. The programmer seems to be pretty open on the content front, with artists ranging from Sugarcult, The Kinks, Athaneum, Zeppelin and others out both in and outside the powerpop field.
Jet City Radio - out of Seattle, and focusing primarily on "oldies" from the 60s and 70s.
Powerpop Radio - out of Georgia. Good programming, and a good place to go to hear many of the "core groups" of the powerpop world.
Popbang Radio - out of Minnesota. Like Powerpop Radio above, but going deeper into lesser known acts and newer releases.
