Updated Version :) Now shows the progress!

let total = 0;
let left = 0;
let interval = 10  // wait time between chunks in seconds

const ytmLog = msg => console.log(`[YTM Liker] ${msg}`);

const chunk = size => array => array.reduce((result, item) => {
    if (result[result.length - 1].length < size) {
        result[result.length - 1].push(item);
    } else {
        result.push([item]);
    }
    return result;
}, [
    []
]);

function likeAll() {
    let els = document.getElementById("contents").querySelectorAll(
        "button[aria-pressed=false][aria-label='Like']");

    total = els.length; left = els.length;
    ytmLog(`Total Queue: ${total}`);

    let cels = chunk(5)(Array.from(els));
    cels.forEach(function(items, index) {
        setTimeout(function() {
            ytmLog('Liking next chunk.');
            items.forEach(el => el.click());
            left = left - 5;
            ytmLog('Chunk finished. Waiting to start the next.');
            ytmLog(`${left} songs left out of ${total}.`);
        }, index *
        interval * 1000);
    });
}

likeAll();

Haven't done enough testing so sometimes the numbers may be wrong, but it worked :)

Output:

For those who get no songs by running this script: just check your language is set to English, so that YT music webpage has aria-label='Like' elements

Be careful using this script. I used it when transferring my music to a new account, and my channel got suspended because YouTube thought I was doing "Fake Engagement" by automating likes.
