Since some of the suggestions were quite commercial ie:association, 
mamas/papas, I'm surprised nobody even mentioned Bacharach, except 
that it may be too obvious to suggest.  Here's one of my favorite 
commercial soft-pop ventures that might have gotten away from some of 
you soft pop fans....
"What the World Needs Now" Stan Getz Plays Bacharach and David - 1967
I still listen to the lp of this I stole from my parents nearly every 
week.  Amazon says it's available on cd; I can't speak to the song 
quality.
Francis Albert Sinatra / Antonio Carlos Jobim is another favorite. 
The reissue of this is one of the most spectacular sounding things my 
stereo has ever experienced
