Pipeline for song genre prediction: II

Having set up the steps of the pipeline in the previous exercise, you will now use it on the music_df dataset to classify the genre of songs. What makes pipelines so incredibly useful is the simple interface that they provide.

X_train, X_test, y_train, and y_test have been preloaded for you, and confusion_matrix has been imported from sklearn.metrics.
