Answer by taking a quote from the following article:

Ray Charles Robinson (September 23, 1930 - June 10, 2004), known professionally as Ray Charles, was an American singer-songwriter, musician, and composer. Among friends and fellow musicians he preferred being called "Brother Ray". He was often referred to as "The Genius". Charles was blind from the age of seven.

Charles's renewed chart success, however, proved to be short lived, and by the 1970s his music was rarely played on radio stations. The rise of psychedelic rock and harder forms of rock and R&B music had reduced Charles' radio appeal, as did his choosing to record pop standards and covers of contemporary rock and soul hits, since his earnings from owning his masters had taken away the motivation to write new material. Charles nonetheless continued to have an active recording career. Most of his recordings between 1968 and 1973 evoked strong reactions: people either liked them a lot or strongly disliked them. His 1972 album A Message from the People included his unique gospel-influenced version of "America the Beautiful" and a number of protest songs about poverty and civil rights. Charles was often criticized for his version of "America the Beautiful" because it was very drastically changed from the song's original version.  In 1974, Charles left ABC Records and recorded several albums on his own label, Crossover Records. A 1975 recording of Stevie Wonder's hit "Living for the City" later helped Charles win another Grammy. In 1977, he reunited with Ahmet Ertegun and re-signed to Atlantic Records, for which he recorded the album True to Life, remaining with his old label until 1980. However, the label had now begun to focus on rock acts, and some of their prominent soul artists, such as Aretha Franklin, were starting to be neglected. In November 1977 he appeared as the host of the NBC television show Saturday Night Live.  In April 1979, his version of "Georgia on My Mind" was proclaimed the state song of Georgia, and an emotional Charles performed the song on the floor of the state legislature. Although he had notably supported the American Civil Rights Movement and Martin Luther King, Jr. in the 1960s, Charles was criticized for performing at the Sun City resort in South Africa in 1981, during an international boycott protesting that country's apartheid policy.

Did he have any other songs? (and yes, a very busy man.)
