Although the teaser only showed member Chanyeol playing the mobile app as music plays in the background, the single is expected to follow "Miracles in December," EXO's holiday special single that topped the charts last Christmas season.

Aside from a holiday special single, EXO-L will receive a much bigger present. The band's first concert album "EXOLOGY Chapter 1: The Lost Planet" will be out on December 22.

This album will feature many tracks from The Lost Planet in Seoul held on three consecutive days from May 23-25 at the Seoul Olympic Park's Gymnastic Stadium. The physical album will come in 2 discs with a total of 36 songs. It will also include hit songs like "Wolf", "Growl" and the latest one, "Overdose".

During the 2014 Mnet Asian Music Awards, EXO received four awards: Best Asian Style, Best Male Group of the Year, UnionPay Artist of the Year and the major prize, Album of the Year for Overdose.

Thousands of people watched their performance in the same event with songs "Tell Me What is Love", "Black Pearl" and "Overdose". At the end of the performance, the audience watched a teaser hinting their comeback in 2015.

Chinese member Chen also sang "Green Light" with SNSD's Tiffany and international guest, John Legend.

These achievements prove EXO's continuously growing popularity despite many critics and rumors after two Chinese members Kris and Luhan filed a lawsuit against the big agency and left the group.

Through these special song and album, EXO ends another successful year as people look forward to an early start next year.
