Als meus avis. Acknowledgements I remember I was quite shocked when, one of the very first times I went to the MTG, Perfecto Herrera suggested that I work on the automatic identification of versions of musical pieces. I had played versions (both amateur and pro- fessionally) since I was 13 but, although being familiar with many MIR tasks, I had never thought of version identification before. Furthermore, how could they (the MTG people) know that I played song versions? I don’t think I had told them anything about this aspect... Before that meeting with Perfe, I had discussed a few research topics with Xavier Serra and, after he gave me feedback on a number of research proposals I had, I decided to submit one related to the exploitation of the temporal information of music descriptors for music similarity. Therefore, when Perfe suggested the topic of version identification I initially thought that such a suggestion was not related to my proposal at all.
