🎶 Music Genre Classifier 🎶

Next time you think of how **Shazam** finds the name of a song, well it might certainly be classifying the genre of the music too. 

This tool classifies music based
on pre-defined genre from the [GTZAN](https://huggingface.co/datasets/marsyas/gtzan) dataset, 
which contains music from the following genres:
`blues, classical, country, disco, hiphop, jazz, metal, pop, reggae, and rock`.
