This year's conference included one paper, three posters and one demo describing research carried out at the MTG.

For its second consecutive year the submission by Joan Serrà, in collaboration with Emila Gomez and Perfecto Herrera, for the Audio Cover Song Identification task scored the best at MIREX, which is the Music Information Retrieval Evaluation eXchange that happens in the context of ISMIR. The system that they submitted this year included some important modifications and parameter tuning with respect to last year submission and it obtained the best results in all evaluation measures considered. Its accuracy also proved to be statistically significant in comparison to the other systems in this task.
