Abstract: Accurately quantifying the goodness of music based on the seemingly subjective taste of the public is a multi-million industry. Recording companies can make sound decisions on which songs or artists to prioritize if accurate forecasting is achieved. We extract 56 single-valued musical features (e.g. pitch and tempo) from 380 Original Pilipino Music (OPM) songs (190 are hit songs) released from 2004 to 2006. Based on aneffect sizecriterion which measures a variable's discriminating power, the 20 highest ranked features are fed to a classifier tasked to predict hit songs. We show that regardless of musical genre, a trained feed-forward neural network (NN) can predict potential hit songs with an average accuracy ofΦNN= 81%. The accuracy is about +20% higher than those of standard classifiers such as linear discriminant analysis (LDA,ΦLDA= 61%) and classification and regression trees (CART,ΦCART= 57%). Both LDA and CART are above the proportional chance criterion (PCC,ΦPCC= 50%) but are slightly below the suggested acceptable classifier requirement of1.25*ΦPCC= 63%. Utilizing a similar procedure, we demonstrate that different genres (ballad, alternative rock or rock) of OPM songs can be automatically classified with near perfect accuracy using LDA or NN but only around 77% using CART.
