Prefer official version of song in search results, sort by YouTube views

Adjusting the search results to include the words "official" or "album" in search would make it more likely that the top result was the video from the artist's YouTube account.

It would also be nice to lower results for titles with keywords like "live", "session", "radio", and variations on date formats (5/1/2020, 5.1.2020, May 1 2020, etc.). 

It's not that I never want to play a live version of a song, but I think most users are more likely to prefer to play the recorded version of the song.
