Rookie girl group Sonamoo has shot to the top of the Gaon weekly album sales chart with the debut mini album release “Deja Vu.”

The six-track album dropped on December 29, but raced to the top of the top of the chart for the period December 28 to January 3, marking a very successful debut so far for the new TS Entertainment act.

“Deja Vu” staved off some stiff competition from the likes of EXO, whose album “EXOLOGY Chapter 1: The Lost Planet” ranked at Number Two, followed by a live album by SHINee and releases by Lee Jae Hoon and A Pink.

A spokesperson for the agency explained, “Some of the girls have been training for four years or longer, and you can really hear that in the album. That is what has caught the fans’ attention. Sonamoo’s music is fresh and vital.”
