I stumbled across the site for the first time perhaps 6 months ago on a whim, while looking for Celtic music on Live365. At the time, I thought, "This is pretty cool," but only listened infrequently. About a month or two ago, I began tuning it in increasingly more frequently, listening over the DSL in my office, sometimes all day.
I have found the playlist to be an incredible relief from the other stuff I've listened to, to get me through the day. And I think I might even appreciate it even more while websurfing in the evening.
I appreciate your desire to keep it free. There is much that could be said about that, but this is not the time. I am guessing that the community of listeners you might attract is relatively small, but it is also probably more inclined to supporting a good thing like this than folks who listen to some other genrés. Whereas I would have no desire at all to pay to subscribe to "premium" service with someone like Live365 or Real, what you've got going here is "pretty cool", and I'd like to have it more consistently available on broadband.
Thanks for what you're doing.
