Deletion of It's a Sunshine Day

Comment: seems to be the best alternative to deletion, however I'm not sure of the proper target.  The song certainly does not have any coverage that shows it to be independently notable, but as a song from a popular series, it seems like it would be a plausible search term.  I was initially going to suggest a redirect to It's a Sunshine Day: The Best of the Brady Bunch, a 90's album that the song was included in, however that album itself suffers from severe sourcing issues and may not pass , and just redirecting it to The Brady Bunch seems a bit too broad
