Does what it says om the tin, upping this to a 5 after a quick response and update from the creator.

This extension is broken for YouTube compared to the development version at https://github.com/OdysseasKr/UltimateSpotifySearch

Users should download and manually add the extension from source to get it working on YouTube again.

Some details: This commit https://github.com/OdysseasKr/UltimateSpotifySearch/commit/57ef3e7e2a30af04676f26c7e14aa8b473ede8e2 updates the search URL.

Otherwise, this extension works as advertised :)

Thanks.
