My husband and I own and operate Mouse House Radio. We didn't think we were going to be able to stay broadcasting but as of now - we still are. If the royalties go up much more that will change - but as of now we can manage it.
We are broadcasting straight from our website - or you can find us (and some others) on Shoutcast. It is probably the most similar format to Live365. Some stations have moved to Radionomy. We thought about it but due to a lot of restrictions (track length has to be under 15 minutes.. meaning we would have to butcher tracks like Wishes etc) we decided to pay the royalties and host with a shoutcast friendly server.
I sincerely hope many others make it through this storm as well. Today is a very sad day as Live 365 went silent around 2:30am central time.
