Overthinking it?

I was in the shower yesterday and had the radio in my room jacked up really high so I could hear it over the water. I was listening the Dave FM when they started playing "Mercy," the new single by Duffy. Now, I really like this song. It's a lot of fun with a great blend of sounds, and Duffy really has a great voice. Please correct me if I am wrong, but does this song sound somewhat like something off of a porn soundtrack? (No, I have not watched porn, but a certain local college radio station has been known to play such tunes.) Maybe I have this connotation because the song was used in an episode of ER when two characters were going at it in one of the recovery rooms in the ER. Just an observation.
