"Wait" is a song recorded by the 1960s rock and roll group The Beatles, from their album Rubber Soul. The songwriting credit is Lennon-Mc Cartney, and is one of the real joint efforts between the two (John wrote the verses and refrain in F# minor, and Paul wrote the bridge in A major). It is a simple love song about a couple who have broken up but are now back together.
"Wait (The Whisper Song)" is a noted snap song released by Atlanta crunk rap duo The Ying Yang Twins off their album U.S.A. (United State of Atlanta). Consisting of a minimal bass pulse and a few finger-snaps, it featured the Ying Yang Twins toning down their usual loud crunk howls for a new whisper approach.
