Did a tampermonkey script that uses ytm2spotify.com to parse any spotify URL when clicked, then it will send you automatically to the first result on the youtube page.

Install it here: https://greasyfork.org/en/scripts/538249-spotify-to-youtube-redirector

Once its installed, test it with this link. https://open.spotify.com/track/6gb4OcL7ILY32IE68rNpQN

It should open on youtube.
