The favorites section is where you manage your 1-Credits songs, per venue. You can view which songs are currently 1CR, move popular or requested songs to 1CR and remove unpopular songs from 1CR.
You can do this manually using the Search options, or quickly fleet wide using various parameters using the "Quick Manage" button.
You are allowed up to 2000 songs in the 1CR Favorites list. We recommend managing this content periodically; of nothing else, to remove unplayed music - keeping the Favorites section relevant and fresh.
