This code is odd because it gets the array element and the index. The
body of the loop then indexes the array. Why not either only get the
index or, better, only get the element?

This code is even odder because neither $year nor $show change in the
loop. It will either do the same as the first loop and print every song
for every year, or it will print nothing at all.

I suspect that $year is a typo. Maybe it should be something like
$item['year']?
