Index number ascension??

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

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.

I thing I get the first line of the loop, I'm more confused/wondering what would the index number be for song #2 and artist #2..etc.

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.
