Here is the original requirement:

Modify any of the sort algorithms to sort a secondary array B based on
the sorting order of A (that is akin to say: sort the titles of the
songs (B) based on their rank (A).

I chose to add Artist info in addition to song title. This is why I
specifically added the #_ (read as number underscore) to the String
array else I figured there was no easy way to sort them based on a
rank. Meaning, you can't compare an int to a String. In my mind, I
thought that adding the #_ to the beginning of the String item would
make it easier to sort it. Does that make sense?
