wish helps you How to write a code for printing Single linked list in reverse order? , You can write a recursive method:
code :
public static void printReversed (Elem start)
{
    if (start.next != null) {
        printReversed(start.next); // print the rest of the list in reversed order
    }
    System.out.println(start.data); // print the first element at the end
}

To fix this issue
code :
void nodeType::PrintListReverse()
{
  if (next)
     next->PrintListReverse();
  std::cout << info << std::endl;
}
void linkedListType::PrintList()
{
    std::vector<int> info(length);
    nodeType* curNode = first;
    for (int i = 0; curNode != NULL; i++, curNode = curNode->next)
    {
        info[i] = curNode->info;
    }
    for (int i = length-1; i >=0; i--)
    {
        std::cout << info[i] << std::endl;
    }
}

To fix this issue To create reverse copy of a single linked list copy one element after another and add it at front of reverse list:
code :
DoubleNode* reverseDoubleListCon( DoubleNode* head) {
    DoubleNode *reverse = NULL;
    while ( head )
    {
        DoubleNode *temp = malloc(sizeof(DoubleNode));
        temp->data = head->data; // copy data to new element
        head = head->next;       // step one forward
        temp->next = reverse;    // successor of new element is first element of reverse list
        reverse = temp;          // head of reverse list is new element
    }
    return reverse;
}

DoubleNode* reverseHead = reverseDoubleListCon( head );
 DoubleNode* reverseDoubleList( DoubleNode* head) {
    DoubleNode *reverse = NULL;
    while ( head )
    {
        DoubleNode *temp = head;  // next element is head of list
        head = head->next;        // step one forward
        temp->next = reverse;     // successor of next element is first element of reverse list
        reverse = temp;           // head of reverse list is next element
    }
    return reverse;
}

head  = reverseDoubleList( head );

To fix the issue you can do Not sure what you are asking. Your implementation looks almost just like the one in the link. Both implementations are O(n) for time complexity, and O(1) for space complexity. Of course, the list itself is O(n) for space complexity.

To fix this issue If you have a single (forward) linked list, the probably easiest way to print it in reverse order is using recursion:
code :
void display_recursive(node *n) {
    if (!n) {
      return;
    }
    display_recursive(n->next);
    printf("Song: %s, ", n->songName);
    ...
}

hope this fix your issue No. The linked list has not concept of a sort order other than the order that the items were created. It's meant to be fast for traversing and adding many items. I am not sure that this data structure suits your needs at all.
I am not sure what your requirements are. Maybe if you could list the requirements we could make some suggestions.
