Following A Great Big World’s performance with Aguilera on The Voice, last week, "Say Something" debuted at No. 1 on Billboard’s Digital Songs chart.

The band’s debut full-length album Is There Anybody Out There? will be released in January 2014 and has fans already waiting anxiously in anticipation.
