Remix album
A remix album is an album consisting of remixes or rerecorded versions of an artist's earlier released material. The first act who employed the format was American singer-songwriter Harry Nilsson ("Aerial Pandemonium Ballet", 1971). As of 2007, the best-selling remix album of all time is Michael Jackson's "" (1997). History and concept. "Aerial Pandemonium Ballet" (1971) by Harry Nilsson is credited as the first remix album. It was released after the successes of "Everybody's Talkin'" and "The Point!", when he decided that his older material had started to sound dated. In the 1980s, record  companies would slap together several kinds of electronic dance music, such as dance-pop, house, techno, trance, drum and bass, dubstep, hardstyle, and trap into full-length albums, creating a relatively low-overhead addition to the catalogs and balance sheets. Since this time, this kind of release is not only seen as an easy cash-in for an artist and their label, but also as an opportunity to provide a second lease of life for a record. In the world of reggae music, it is not uncommon for a whole album to be remixed in a dub style. Jennifer Lopez 's album "J to tha L–O! The Remixes" is listed in the "Guinness Book of World Records" as the first remix album to debut at No.1 on the Billboard 200 chart.
