NEW YORK:

Just in time for Valentine's Day, Billboard has ranked the 50 sexiest songs by popularity and Barry White didn't even make the list.

Instead, it's Olivia Newton-John who is tops - her hit Physical is No. 1, followed by Rod Stewart's Tonight's the Night (Gonna Be Alright).

Rounding out the top five: Boyz II Men's ballad I'll Make Love to You, Next's Too Close and Marvin Gaye's Let's Get it On. (Gaye's Sexual Healing is No. 35)

It's not until No. 10 - Stewart's Da Ya Think I'm Sexy? - that sex is mentioned in any song title.

Billboard's list, released Thursday, is based on the popularity of songs from 1958 until early January of this year.
