The guys in Delirious have a free song (from their upcoming album Kingdom of Comfort, April 2008) available for download. The song is called "God is Smiling", and the guys had this to say about where you can obtain it. According to a recent update:
"The treat is located in a brand new free members-only section called The Living Room. On top of that The Living Room will feature band blogs, galleries, videos with more features being added weekly. All that it takes to get in the room is a simple registration, once that's taken care of members will be right at home.
