The document discusses literature on classifying music genres using neural networks. It summarizes several past studies that used techniques like convolutional neural networks (CNNs) and mel-frequency cepstral coefficients (MFCCs) on datasets like GTZAN to classify music into genres like blues, classical, country, etc. The document also outlines the system design for a proposed music genre classification system, including collecting the GTZAN dataset, preprocessing the audio files into mel-spectrograms, extracting features using MFCCs, and training a CNN model to classify segments of songs into genres. Classification accuracy of different models from prior studies ranged from 40-80%.
