for (i = 0; i < totalsongs * 2; i++) {
  int j = rand() % (i + 1);
  char swap[MAX_LENGTH];

  while (!check(j, doubled)) {
    j = rand() % (i + 1);
  }

  // Update the shuffled playlist
  strcpy(swap, doubled[i]);
  strcpy(doubled[i], doubled[j]);
  strcpy(doubled[j], swap);
}

printf("Shuffled playlist:\n");
for (int i = 0; i < totalsongs * 2; i++) {
  printf("%s", doubled[i]);

bool check(int j, char doubled[24][80]) {
  int max = j - 5;
  if (max < 0) {
    max = 0;
  }
  for (; max < j; max++) {
    if (strcmp(doubled[j], doubled[max]) == 0) {
      return false;
    }
  }
  return true;
