Up here in Rochester we get the Thistle and Shamrock. Pleasant and dependable.

We also get a nice collection of live "celticly" bent bands at the local pubs, brew houses and the like.

For dependability I use live365 or shoutcast.com for streaming because I like the variation and I am always looking for different music.

If you haven't tried it Pandora is pretty good at what they do even though their selection seems to be a bit thin still.
