There 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.

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