"I Don't Want To Set The World On Fire" - The Inkspots (a personal fave)

"Today" - Jefferson Airplane

"At Last" - Etta James

"This Girl's In Love With You" - Dionne Warwick

"More Than Words" - Extreme

It's hard to avoid Joe Cocker's "You Are So Beautiful"...pretty drippy.

If you were including lamenting-love songs, I'd add "Oh! Darling," by the Beatles, and "Suite: Judy Blue Eyes" by Crosby, Stills & Nash. Tons more of those.
