We are now ready to apply the previous graph clustering method to the cluster music songs, according to the tags attached to each song.

train.txt: This file contains the playlist data by using the integer ID to represent songs
tags.txt: This file includes the social tags by using the integer ID to represent songs
song_hash.txt: This file maps a song ID to its title and artist
tag_hash.txt: This one maps a tag ID to its name ...
