The Pulse of Radio reports: Christmas may be a time of celebration and joy for many people, but according to the members of APOCALYPTICA, that's not the case in their native Finland. The holiday comes during a period in which the northern country doesn't get any sunlight for up to four months, and APOCALYPTICA member Eicca Toppinen told The Pulse of Radio that leads to more problems. "Finland is number one in suicide numbers in the world," he said. "Christmas is the worst time for that, and it seems to be very hard because the dark period lasts for three to four months every winter. And all these lonely people, you know, they're already depressed, and when it comes to the time of Christmas, they can't stand it."

APOCALYPTICA scored their first No. 1 rock radio hit last month with "I Don't Care", the latest single from the band's sixth studio album, "Worlds Collide".

The disc has sold 153,000 copies in the U.S. and marks the rock cello quartet's first significant success in this country in their 15-year career.

"I Don't Care" features guest vocals from THREE DAYS GRACE frontman Adam Gontier, while SLIPKNOT's Corey Taylor contributed vocals to the CD's first single, "I'm Not Jesus".
