This actually works! I can't quite believe it. Finally an addon that actually works. Thanks. As the other review says, would be nice for the tab to close once opened in the Spotify desktop app but this'll do for now!

Works really well. Really needed this as an avid user of RYM and Spotify. I hope this gets more updates and I wish there was an option for the link to be automatically closed in the browser when it opens up on the desktop app. Thanks!
