At the center of the site, you'll see a input field. This is meant to navigate to new or existing channels. If you input something here that doesn't exist, a new channel will be create at the blink of an eye! Remember to put a password on the list you've created, so no one else takes it from you! (It's on a first come, first serve basis). When you're ready to proceed, just click the listen button!
Underneath the input fields, there are several tiles. These are channels that already exists, and they can be clicked! To listen to one of these channels, it is just to click the tile.
If you want to listen to the channel without any "hickups", or being affected by other peoples votes, there is a local mode. By clicking the local button in the header, you will be free of synced listening!
