A topic of music information retrieval (MIR) field is query-by-example (QBE), which searches a popular music dataset using a user-provided query and aims to find the target song. Since this type of MIR has been generally used in online systems, retrieval time is also as important as accuracy. In this paper, we propose a QBE-based MIR system and investigate the impact of automatic music genre prediction on the performance of it, specifically on perspective of accuracy-time trade-off, using a score-based genre prediction method as well as similarity measures. The proposed system is evaluated on a dataset containing 6000 music pieces from six musical genres, and we show that how much improvement on the performance can be achieved in terms of accuracy and retrieval time, compared with a typical QBE-based MIR system that uses only similarity measures to find the user-desired song.
