Stephen Pearcy intentionally strayed from saccharin-sweet schmaltz while not crossing the line into sleaze. Musically, this song finds Ratt exhibiting the swagger of Aerosmith streamlined by the pop sensibilities of the Beatles. This versatility showed the world that they hadn't lost their touch while making their second album. "Lay It Down" was the first single released to promote their second album, Invasion of Your Privacy.
This song reached #40 on the Billboard Hot 100 during the summer of 1985, becoming Ratt's second (and last) Top 40 hit. It continued Ratt's success in the world of rock music, which would not cease until the dawn of the following decade. The song was co-written by Ratt vocalist Stephen Pearcy, bassist Juan Croucier, and guitarists Robbin Crosby and Warren DeMartini.
