Recently, the amount of music that can be heard is increasing exponentially due to the growth of the digital music market. Because of this, online music service users have had difficulty choosing their favorite music and have wasted a lot of time. In this paper, we propose a recommendation technique to minimize the difficulty of selection and to reduce wasted time. The proposed technique uses an item - based collaborative filtering algorithm that can recommend items without using personal information. For more accurate recommendation, the user's preference is predicted by using the metadata of the music source and the top-N music with high preference is finally recommended. Experimental results show that the proposed method improves the performance of the proposed method better than it does when the metadata is not used.

본 논문은 온라인 음원 서비스 이용자들이 겪는 선택의 어려움을 최소화하고, 낭비되는 시간을 줄이기 위한 음악 추천 기법을 제안하고자 한다. 제안하는 기법은 개인정보의 이용 없이 아이템을 추천할 수 있는 아이템 기반 협업필터링 알고리즘을 사용한다. 더 정확한 추천을 위해 음원의 메타데이터를 이용한다. 실험을 통해 제안하는 기법이 메타데이터를 이용하지 않을 때보다 추천 성능이 향상되는 것을 확인하였다.

Rapid technological innovation led by digitization has significantly changed the business of digital content goods, and has led to the emergence of new forms of services, such as music streaming. However, whether the streaming service is a threat to the traditional downloading service is still under debate. In this study, we examine whether music downloading is a substitute for or a complement to music streaming by investigating the moderating effects of LTE technology penetration. Using a unique dataset on the online music market from a dominant music platform in Korea, we found that music downloading services are complementary to music streaming services, but this complementary relationship is significantly and positively moderated by the introduction of LTE technology.

As a result of growth of digital music market in Korea, Creator's rights and interests have been at the heart of the debate in terms of legal system. In the music industry, digital music revenue has now overtaken records sales and compared to download service it is now clear that music streaming and subscription is mainstream model in the rise of the worldwide market of digital music. This trend is also indentical to the domestic and withholding regulations for music service and creator's rights and interests have become an ever growing issue. Ministry of Culture, Sports ad Tourism decided the revision of withholding regulations for the digital music service in 2013. The amendment is to change its policy of charging music service from the flat rate pricing to a usage-based system. This paper brought forward some disputable points such as fair division of profit, reasonable pricing for consumers etc. about the revision. Therefore, improvement of system and change in the perception of such copyrights are still required for both the encouragement of creator's activities and the high consumer satisfaction.
