Music on Hold - Radio Stations?

I've been using voip phones at home for just over a month and i was wondering if anyone has some music on hold url's that work, or if anyone knows how to obtain a url from streaming radio site and has been able to get it working with your voip phones.

I have this working on my phone at present. It's far from great, but is ok.
