Cover versions (Music) now showing on Google Search

Google has quietly updated its music title extended info box results to display Cover versions of Chart hits (with live links to YouTube) When you click through to one of the cover results, it goes to a new page that shows the various cover versions in a rich list, with a YouTube video of the selected cover below.

DuckDuckgo does something similar the scrolling bar if Videos are selected often shows other Artists versions when scrolled along

All the rest I tested do return original versions only :(
