Write a song that becomes the signature tune for a blockbuster movie.
Wiki
"Everybody's Talkin'" is a folk rock song written and originally released by Fred Neil in 1966. A version of the song performed by Harry Nilsson became a global success in 1969, reaching #2 and #6 on the Billboard Adult Contemporary chart and Pop Singles chart respectively, and winning a Grammy after it was featured on the soundtrack of the film Midnight Cowboy. The song, which describes the singer's desire to retreat from other people to the ocean, is among the most famous works of both artists, and has been covered by many other notable performers.
Pretty good deal for Fred as he didn't like touring and retired to Florida and spent his time searching for the dolphins.
I'm not the one to tell this world
How to get along
I only know the peace will come
When all hate is gone
