If you haven't added any Events to your Schedule, you can still broadcast by putting your Live365 station into AutoDJ mode.
When AutoDJ is enabled, your station will randomly play tracks from your library, keeping in compliance with the DMCA and automatically inserting ads (if you are part of the Advertising Revenue Share Program. The AutoDJ feature is enabled by default. You can read more about the AutoDJ settings here.
You can take control of your station at any time by scheduling an Event and filling it with a DMCA-approved Playlist, or by using the LiveDJ credentials to broadcast live using a 3rd-party software. For more info on broadcasting live, see this page.
