eJay is a series of musical arrangement[1] software, and video games, primarily for Microsoft Windows. The first edition, Dance eJay, was released in 1997.[2] It supports eight tracks of audio and, as with its successors, permits the arrangement of sound bites by a drag-and-drop interface.[1][3] Since the original Dance eJay, there have been many releases catering to different music genres and users, including techno[4] and hip-hop,[5] as well as a PlayStation 2 edition called eJay Clubworld.[6]
