A record contract is a legally binding, written agreement between you and a record company stating how money from the sales of your songs should be divided and who owns the rights to the work.
Copyright gives the owner of a song legal control over how their work is used. It allows the owner to earn money by directly selling their music, or to transfer the copyright to a third party who will sell it on their behalf.
