The International ACM Workshop on Music Information Retrieval with User-Centered and Multimodal Strategies (MIRUM) at ACM Multimedia was proposed in order to gather experts from the Music and Multimedia Information Retrieval communities, as well as other neighboring fields, and to provide a high-profile platform for presenting current work on Music Information Retrieval with a strong focus on user-centered and multimodal approaches. Following a successful first edition at ACM Multimedia 2011, a second edition of MIRUM was held at ACM Multimedia 2012, which is the focus of this overview. After a description of the rationale and focus areas of the workshop, the accepted submissions and other program elements are summarized.@en
