Again & Again (2PM song)

"Again & Again" is a dance-pop song with R&B elements composed and written by Park Jin-young. The song was recorded over the course of a week at JYP Entertainment's New York branch, where local staff members including Grammy Award-nominated Vlado Meller assisted in the post-production and mastering process.^[1] The lyrics of the song are from the perspective of a man who cannot stop thinking about and going back to a woman who broke his heart.^[1][2]

The track would later be included in 2PM's first studio album, 01:59PM, released on November 10, 2009.^[3] Another version of the song was recorded without former 2PM member Jaebeom's vocals to be included in the 2012 compilation album 2PM Member's Selection.^[4]

The music video alternates between scenes of the members individually following and watching a woman, who walks with another man into her house, and scenes showcasing the song's choreography with three different backdrops: one with radiating lines of lights, one with nested squares at different angles, and one with a curved backdrop. The ending features a dance break sequence involving acrobatic stunts and breakdancing.^[6]
