Good Charlotte announced yesterday their fifth album, "Cardiology", will be released on October 26th on Capitol Records, after severing their relationship with Epic, the home of their first four albums. The first single from the album is entitled "Like It's Her Birthday" and should be released by the end of August. 

"All of these songs have big hooks and feel good," frontman Joel Madden said in a recent interview. "We wanted a whole album of singalongs."

Good Charlotte are scheduled to perform several European shows this month, including opening for Pink at a July 23rd show in Sweden, and plan to launch a US tour early next year.
