Album information:
Slow-speed records are a type of CD, and the playback equipment is the same as ordinary CDs, with no special requirements. Mini albums are slightly different from ordinary CDs. Each mini album contains fewer tracks than CDs, usually about 5 songs, and the price is lower than ordinary CDs.
The mini album does not have as many songs as the regular album, nor is it as well produced as the regular album. It has about 5 songs. It is an intermediate form between a regular album and a single.
Many singers release mini-albums because they don’t have enough time to complete a full-length album, but they really want to share their very fulfilling music with their fans. Others just want to make some money.
Albums in this format are more common in Korea recently, but relatively few in Japan.
