Doing work on CustomPress Output

So here's the issue I've got. I've used custompress to create a multiline text field. The idea here is to list the songs of an album in a list format. The problem I'm running into is that custompress's shortcodes treat the input as a single paragraph element. So when I check the inspector the line breaks are, indeed, preserved but they're output as a single line.

What I'd like to do then, is write a short bit of php in my "albums" template that would take the single paragraph element, explode it into an array, and output that array into a div of my own design.

So my first question then is how can I get the output of the custom fields? Can I just use get_custom_fields?

So something like this?

<?php

  $custom_fields = get_post_custom($post_id);
  $my_custom_field = $custom_fields['custom_field']; // I assume this will just have the one string in its array?
$songsList = preg_split('/\r\n|\r|\n/', $my_custom_field[0]); // this should give me an array of strings divided accordingly yeah?
echo '<div class="song-list">';
foreach ($song as $key => $songTitle)
{
   echo '<div class="album-song">' . ($key + 1) . '. ' . $songTitle . '</div>';
}
echo "</div>"

?>

Is that right? I'm not used to getting information from WP yet.
