What are you trying to do? Pick one song randomly?

Then look at your array:

echo $top[1960][1][0] would give "Theme From A Summer Place"

Just put rand(0,9) as index of the third level, and the rest ... don't know what you
want.

And it is quite near to PHP array abuse, there must be a better representation.
