We get this question a lot recently. Its actually a really good way to get traffic flowing to your radio station easily.
Its all automatic and as long as your radio station is set to “public” in your live encoder or your auto DJ system, you will be placed in their directory automatically. However you need to be in the SHOUTcast top 500 stations. This means your stream needs to be pulling in on average 50 simultaneous listeners throughout the day.
