You can only have one skill by the same name, and you can only have a live stream associated with one skill. So, you could not for example, have 3 skills called Rock 101, Rock 101.1 and Rock 101 Antown all playing the same stream. Therefore it's important to pick your one favorite name to try first. Update: in recent days Amazon has been allowing now only two skills with the same name, but multiple skills with the same source (stream). So for now at least, you COULD release multiple skills with various names and the same stream. For example, you could release Sunny 108, Sunny 108FM and Sunny 108 Anytown as redundant skills. However, this is an ever-changing landscape and Amazon may change their rules at any time.
