Three years after making their last comeback, Big Bang seems to feel like calling themselves "Loser."

YG Entertainment's top male idol group Big Bang previewed two songs from its upcoming "Made" series during a concert in Seoul on April 25. The group also revealed one music video. Videos of the songs, "Loser" and "Bae Bae," were uploaded by concert attendees to YouTube.

The two songs will officially be released on May 1.

The song titles and release dates were confirmed on YG Entertainment's YG-Life blog. YG-Life called it "Big Bang Made Series M" and announced the digital and physical release of "Loser" and "Bay Bae" will take place on the same day.

The poster also showed the five Big Bang members in retro-styled outfits, with each member sporting embellished clothing and new hair styles.

Videos of Big Bang performing "Loser" and "Bae Bae," as well as the music video of "Loser," were uploaded by fans who attended the Big Bang concerts on April 25 and 26 at Seoul's Olympic Park Gymnastic Arena.

"Loser" and "Bae Bae" are Big Bang's first collaborative music releases since 2012's "Still Alive" repackaged album. The group will release new music on the first of each month through September 1.

Despite no group releases since 2012, the five Big Bang members have toured together and appeared in concert together. Each member also focused on their solo careers, with YG Entertainment releasing solo songs and albums from all five members.

The full album "Made" will be released on September 1.

Comments on the poster shared on Facebook by YG-Family's official page expressed a variety of reactions, and noted that Big Bang's consistent releases will ensure the group's place on Korean music charts throughout a good portion of 2015.

Other fans humorously commented on the song titles, based on the use of the English slang term "bae."

"Two very contradicting titles," said Jenny Tan. "Did she go from loser to bae or bae to loser?"
