It's Valentine's Day, and love is in the air... on the radio, in the coffee shops and maybe on your iPod.

You know there's that one song that melts your heart every time you hear it. For me, it's "Over the Rainbow," sung by Israel Kamakawiwo'ole. I don't know what it is, but that song makes stop in my tracks whenever those first notes are played.

A colleague of mine and I came up with this list of classic love songs:

• "Wonderful Tonight," Eric Clapton
• "Love Song," The Cure
• "At Last," Etta James
• "Unchained Melody," The Righteous Brothers
• "All I Want is You," U2
