"Let It Rain" is a song co-written and recorded by American country music singer David Nail.

Co-writer Jonathan Singleton, who also co-wrote Nail's 2009 single "Red Light", told the website Taste of Country that they came up with the idea for the song while talking about movies that they enjoyed.

They recalled the film The Last Kiss where "this guy cheats on his girlfriend, and he goes to her house and decides he’s going to sit on her porch until she lets him in."

Instead of having the male narrator say "I deserve whatever I get, if she never talks to me again", Nail decided to have the character say "that I’m human just like everyone else and you mess up".

[4] Bobby Peacock of Roughstock rated it three-and-a-half stars out of five, also saying that the lyrics had "interesting details" and describing Nail as "strong [and] soulful", although he thought that the song's hook did not work because "there's no other 'rain' motif anywhere else".
