Well any song on the Beatles' album Love Songs would cover the second one really. But it depends on the context/theme you're wanting to use it in. Is it a human project? Dog project? Country project?
Lovin' Touchin' Squeezin' is a Journey song that would fit the bill. Lies by Foreigner would work for the third one. She's Always a Woman by Billy Joel would work for the second one. Lonely Is the Night would work for one. Lost in the Supermarket would cover the loneliness and lies category. The Cheeseburger Song would fit every one of those categories.
There's...a ton of songs. A plethora even, that would fit all those categories. Nothing to narrow it down? Can it be vulgar?
