Apparently the 70s and 80s are still major power players on top 10 music lists. Olivia Newton-John's 1981 hit "Physical" has topped's list of the Sexiest Songs of All Time.

"Physical" spent 10 weeks atop the Billboard Hot 100. It was certified platinum and ranked as the biggest song of the decade. Utah radio stations banned it for having provocative lyrics such as: "There's nothing left to talk about/'Less it's horizontally/Let's get into physical/Let me hear your body talk, your body talk."

To counter the song's racy tone, Newton-John made an aerobics-themed music video, making headbands a fashion accessory outside the gym.

The new countdown is based on the performance of songs about sex on the Billboard Hot 100 chart from 1958 until January 2010.

The top 10 are:

Olivia Newton John "Physical" 1981
Rod Stewart "Tonight's The Night 1976
Boyz II Men "I'll Make Love To You" 1994
Next "Too Close" 1998
