Ah Yeah (EP)

On March 4, 2015, Star News reported that Exid was working on a new song, scheduled for release in the second week of April, but it was undecided whether the song would be released as a single or with a mini-album.^[1][2] On April 3, the album's cover art and tracklist were leaked online, prompting Yedang to issue a statement the following day that the company would take legal action if the leak harmed the success of the group's comeback.^[3]

Exid held a showcase at Noon Square in Myeongdong on April 12, where they performed "Ah Yeah" for the public for the first time.^[4][5]

As of October 2015, the album has sold over 18,000 copies in South Korea,^[6] and 7,000 copies in Japan.^{[7][better source needed]}

The album was composed by Shinsadong Tiger, who has been the group's producer since their debut.^[8] Member LE also participated in the album's production, co-writing and composing all the songs on the album. The title track, "Ah Yeah", is a hip-hop style dance song with a repetitive hook. "Pat Pat" is described as an "urban R&B" song and "With Out U" as an "urban dance" song. The album also includes their previous single "Up & Down" as well as a new version of "Every Night."^[9][10]

The first single made headlines for its belated chart run — after initial mediocre success, the song started charting three months after its debut.^[11] The late success of the single was attributed to a fan-cam video of member Hani performing the song, which went viral across Korean social media networks in late November.^[12][13][14]
