Copy SoundCloud playlist items from one to another.

soundCloudPlaylist.js

// Configuration
const WAIT_OPEN_PLAYLIST_POPUP = 1000;
const WAIT_AFTER_ADD_PLAYLIST = 1500;

const TARGET_PLAYLIST_NAME = 'To Do';

// Should the new playlist be in reverse order?
const REVERSE = false;
// Should liked items be skipped?
const SKIP_LIKED = true;


// Implementation
const delta = REVERSE ? -1 : 1;
const nextIndex = (index) => index + delta;

const listItems = Array.from(document.querySelectorAll('.sc-button-group.sc-button-group-small'));

const addItemToPlaylist = (index) => {
    const node = listItems[index];

    if (!node) {
        console.log('Done with all currently loaded items.');
        return;
    }

    if (SKIP_LIKED) {
        const hasLikedButton = node.querySelector('.sc-button-like.sc-button-selected');

        if (hasLikedButton) {
            console.log('Already liked index: ', index);

            setTimeout(() => {
                addItemToPlaylist(nextIndex(index));
            }, 0);

            return;
        }
    }

    node.querySelector('.sc-button-more').click();
    document.querySelector('button.sc-button-addtoset').click();

    setTimeout(() => {
        const playlistRow = Array.from(document.querySelectorAll('.addToPlaylistList__item')).find(node => node.querySelector(`[title="${TARGET_PLAYLIST_NAME}"]`));
        const playListButton = playlistRow.querySelector('button.addToPlaylistButton:not(.sc-button-selected)');
    
        if (!playListButton) {
            console.log('Already added index: ', index);
    
            setTimeout(() => {
                addItemToPlaylist(nextIndex(index));
            }, 0);
    
            return;
        }
    
        playListButton.click();
        console.log('Added index: ', index);
    
        setTimeout(() => {
            addItemToPlaylist(nextIndex(index));
        }, WAIT_AFTER_ADD_PLAYLIST);
    }, WAIT_OPEN_PLAYLIST_POPUP);
};

if (REVERSE) {
    addItemToPlaylist(listItems.length - 1);
} else {
    addItemToPlaylist(0);
}

thank you from the bottom of my heart

With these few changes got it to work.

const WAIT_OPEN_PLAYLIST_POPUP = 1500; // Increased the wait time
const WAIT_AFTER_ADD_PLAYLIST = 2000; // Increased the wait time

const TARGET_PLAYLIST_NAME = 'my playlist'; // Changed name to an already saved playlist
