Introduction to Intelligent Music Systems and Applications

Intelligent technologies have become an essential part of music systems and applications. This is evidenced by today’s omnipresence of digital online music stores and streaming services, which rely on music recommenders, automatic playlist generators, and music browsing interfaces.
