*For Unlimited Plus Plan hosts, the listener limit is 500.
Apart from the host title, there is the host level. Host level is based on your engagement score. The higher engagement score you get, the higher level you are. For those hosts with a higher level, they are more likely to be featured on the live list. (You can go to Stats to check your host title and host level.)
