Loudcity pricing depends on listener-hrs/month (Pricing
Spaceplay is correct - In fact LoudCity is US-only. Althout trust me - it's much easier in the US to use such a service than it is going it alone. WebcasterU is, I believe, looking into a UK plan but that is in the early stages of development.
My station is under 5000 ATH at this time (It's only 10 weeks old), so I use their lowest level, although I pay for custom launch page. That's a nice feature because it makes the transition from my site to launching streams almost invisible.
Since this isn't really a SHOUTcast Tech Support issue, I think we should end this thread here. But if you are curious about what LC offers, I'd encourage you to visit their site, forums etc and chat with other stations there. Same with WebcasterU.
