Carly Rae Jepsen & Owl City -- Still Waging Battle Over 'Good Time' ... Publishing Co. Releases $800K

Carly Rae Jepsen and Owl City are in a dog fight over their hit track "Good Time" -- battling another artist who claims they ripped her off ... and now we've learned more than $800,000 hangs in the balance.
