I'm trying to figure out what the index number would be for each song/artist in the for loop.

229,644 PointsThere are two index numbers involved. The first selects the specific song, and the second one picks which of these you want. The title index is always 0, and the artist is always 1.
In the loop, "i" is used to select the song — so "song[i][0]" is the song's title, and "song[i][1]" is the song's artist.

229,644 PointsThe "i" index is which song, and index numbers start at 0, so ...
first song's title, 
first song's artist
second song's title, 
second song's artist
third song's title, 
third song's artist
song[0][0]song[0][1]song[1][0]song[1][1]song[2][0]song[2][1]... and so on.
