The human composer (in this case Benoît Carré, but we are experimenting with other musicians as well) selected a style and generated a leadsheet (melody + harmony) with a system called FlowComposer. For Daddy’s Car, Carré selected as style “the Beatles”
With yet another system called Rechord the human musician matched some audio chunks from audio recordings of other songs to the generated leadsheets.
Then the human musician finished the production and mixing.
WTF indeed. The system composed something then a person turned it into a bland mess.
Also, the Cardigans already wrote a fine song called “Daddy’s Car”.
