A couple of weeks ago, I posted about mockfreeli.org, a free service that finds license-free music that sounds like songs you supply. Since then, I built a chrome extension to make the service easier to use. Just go to youtube and find a song you like. Open the extension and click Find License-Free Cousins. It will surface five copyright-free songs for free use in videos, podcasts, etc. Check it out! If you like it, leave a web-store review, otherwise, feel free to Mock Freeli!
