Group 2PM held their surprise concert event today in Korea at Gangnam station's M-Stage.

Fans were ecstatic to finally be able to see the group after waiting for 2 years for their comeback.

This '2PM is Back with Genie' concert was held for one hour as they sang many of their hit songs including their new title songs.

They performed their new double title songs, "Comeback When You Hear this Song" and "All Day I Think About You." They also wrapped up the concert by singing some of their past hit songs such as "Put Your Hands Up" and "10 out of 10."

Junho also performed his self-composed song, "Love Song" as well.

It has been 2 years since 2PM has made a comeback, and they have not disappointed their fans. Their new song is catchy and features a more charming and soft image then their usual tough and beastly' image.

Their new album track list revealed that the members had worked together to produce several songs for the album. Taecyeon wrote the rap parts for the songs and Jun.K helped write 2 of the songs. Junho also composed 3 of the songs and Chansung for one of the songs.

With these combined efforts of the group, this album was able to be complete. Their new album is one that they are especially excited and passionate about as they have put in their hard work and effort to release it.

Over the past year, they have been busy performing in Japan and other countries for their 'What Time is It' live tour. They will be holding the 'grand finale' concert to wrap up the tour on June 21-22 in Seoul.

The concert was also streamed live on YouTube on their official channel. You can watch it here:
