This is very interesting - it is almost like bringing YouTube interface into ordinary Google search. It looks quite similar to YouTube and a visitor may almost forget where they are.
I am seeing it on google.com and google.co.uk, but not on other country-specific googles.
To clarify - search for the artist name followed by the word "songs" and you get this interface. Click on any song within the carousel and the big youtube video of the song appears below it.
