Oh, some excellent choices so far! I'm sure there's a huge amount of skill getting all the ingredients right. Good pop is really underrated, don't you think?
Just thought of more that really hit the spot for me:
Everybody Hurts - REM (I'm a HUGE fan of theirs.
) Very moving. ("hold on") Tenderly supportive song responding to another's intense pain. Michael Stipe at his most moving & expressive. (I LOVE his voice!)
The First Time Ever I Saw Your Face - Roberta Flack. Just perfect in every way. As beautiful, gentle "love song".
