You can create a custom playlist a variety of ways via your web portal at rockbot.com:
- Click on the Music icon and select Add Playlist
- Toggle over to Your Music and select Create New Playlist
- Chose one of the 3 options to create a custom playlist: "Start a Blank Playlist", "Import a Spotify Playlist", or "Import from a playlist file" like an iTunes Playlist.
Whether you import from Spotify or a playlist file you can add songs or artists to your custom playlist.
Keep in mind your playlist will need to have at least 20 songs to be able to add it to your station. You are the owner of the playlist, therefore, you are the only one that is able to edit the music inside of it.
