Valentine's Day is Thursday and love songs is a timely subject, but this poll first... caught my attention because they also surveyed people who are divorced or separated about their favorite love song.

Sony Home Audio commissioned this poll by Harris Interactive of the most popular love songs over the past few decades.  But they also asked those who have had relationship troubles to give their feedback.

Surprisingly, the divorced folks didn't choose "I Will Survive", "Since You've Been Gone", "Before He Cheats", or "I Hate Myself For Lovin' You". As a matter of fact they didn't choose any "scorned lover" love song. They picked the same song everyone else picked!

Whitney Houston's "I Will Always Love You" has been voted the most popular love song in America. The song got 38 percent of the vote among all adults in the survey. It was also the top pick among all divorced, separated or widowed Americans.

Houston's hit from her 1992 movie, "The Bodyguard" was a cover of a 1974 song written and recorded by country singer Dolly Parton. This acknowledgement of Whitney come on the first anniversary of her death on February 11th, 2012.

The Righteous Brothers' "Unchained Melody," Percy Sledge's "When a Man Loves a Woman," Joe Cocker's "You Are So Beautiful," and the Bees Gees' "How Deep is Your Love" rounded out the top five songs.

Do you agree or disagree with these choices? Have another song you think deserves consideration as one of the best love songs?  Give me your feedback in the comments section below and Happy Valentine's Day!
