On October 11, girl group MAMAMOO made their long-awaited comeback as a group with their 12th mini album "MIC:ON," made up of "ILLELLA" (the title track, "1,2,3 Eoi" and "L.I.E.C"). After its release, the singles from the album topped and entered iTunes charts in various countries worldwide, and much to the amusement of fans, there was a battler between the title track and a B-side for the top position.

First, the group's b-side "1,2,3 Eoi" decided that it was the title track and over-took all the other album tracks by debuting at no. 4 on the Worldwide iTunes songs chart. Something that was anticipated by the fandom as the song is a special reference to the chant MAMAMOO does right before performing on stage for good luck. Thus even before its release the song was identified by the group's fans as a strong candidate for the favorite song in the comeback.

The song "1,2,3 Eoi" topped various countries at no. 1, such as Brunei Darussalam, Cambodia, Estonia, Indonesia, Lithuania, etc. Furthermore, ranking in the top 5 for Chile, Hong Kong, Malaysia, Mexico, Philippines, Vietnam, Brazil, and others. Closely followed by the comebacks title track "ILLELLA," which debuted at No. 9 on the worldwide iTunes songs chart. Topping countries such as Bahrain, Brazil, Chile, Ghana, Malaysia, Mexico, and others at no. 1. While raking in the top 5 for Indonesia, Singapore, Taiwan, Brunei Darussalam, Colombia, Hong Kong, Peru, and many others. Both songs also went head to head on the European iTunes Song Chart, with "1,2,3 Eoi! (NEW)" coming at no. 12 and "ILLELLA" at no. 26.

The group's 3rd song from the album "L.I.E.C" debuted at no. 29 (NEW) on the Worldwide iTunes songs and was in the top 5 in Malaysia, Philippines, Singapore, and Vietnam. As well as the top 10 in Hong Kong, Taiwan, Indonesia, Romania, and New Zealand.

Moomoos are incredibly proud of the group's comeback so far and can't wait to see how the race between "1,2,3 Eoi" and "ILLELLA" continues in the upcoming days. As both songs continue to increase in various iTunes positions every couple of hours, each seeking to be the victor.
