Much more simple...
No need for the 'advanced' search stuff...
Whenever you search for music info, and you know some of the lyrics, just type the words you know followed by a - (space) and then
lyrics...
as in
YOU GOT TO KNOW TO UNDERSTAND, I'LL TAKE YOU BY THE HAND, I'LL TAKE YOU TO THE PROMISED LAND - lyrics
The result will normally be a great number of sites...
