Popular Korean music has been a hit in the world since the 1990s, when the 'Gangnam Style' of Psy began to hit K-Pop. In 2017, Bang Tan Boys(BTS) are gaining popularity among music fans around the world. As K-pop spreads to music fans around the world, the Korean music industry is rapidly developing. In addition, due to the development of IT technology, the analog music market, which is represented by LP and cassette tapes, has been turned into MP3 digital music market. The development of the digital sound source market has been closely related to the use of PC, MP3 player, and mobile phone, and the sound source market centered on digital sound source has grown rapidly. However, the growth of the digital sound source market was the only market for completed music. As a result, sales channels for songwriting and lyrics have been limited due to the lack of a distribution channel. In this study, we developed a mobile sound source market application that can be purchased by a music producer or an aspiring singer, by publishing a lyric, composition or unpublished digital sound source produced by an expert as well as experts. The application searches by theme, genre, and title so that registered text and sound source can be purchased. We made it possible for the sound producer to buy the sound source through preview and pre-listening. We expect to activate digital sound source production, rational sound source circulation, activation of sound source market and contribute to the growth of the music industry through this application.
