The following SQL:
select * from videos v
left join artists a on a.id = v.artist_id
left join users u on u.id = a.user_id
left join genres g on g.id = u.genre_id
where g.name = 'Acoustic'
is the equivalent to (which works):
Video.find(:all, :conditions => ['genres.name = ?',
'Acoustic'], :includ

left join users u on u.id = a.user_id
left join genres g on g.id = u.genre_id
where g.name = 'Acoustic'
