Help me identify this song?

Okay, I first heard this song on an Aer Lingus flight as the offloading music when we landed at Malaga airport in August 2011, I was convinced it was airline exclusive music because I couldn't find the title anywhere. I tried googling.. I can't contact Aer Lingus about it. They don't have a relevant queries email address.

I heard this song again today when I was buying lunch at the co-op.

The song is something like this

"when you bring out the best in me "

*whistling tune*

Then something else.

It pretty much repeats those two lines over and over.

Please help me find this song!

Thank you.
