Music rights are a type of copyright
Music rights are a type of copyright - a legal term that identifies ownership of specific rights over original creative works like songs and albums, literary works, movies or software. In particular, music rights refer to all legally-binding economic rights vesting in music recordings, musical arrangements, lyrics, song titles, artwork, graphics, song rights or other forms of music-related intellectual property rights.
Songs, their music and lyrics, are creative works that are protected by copyrights. This is the reason why rights owners are entitled to royalties when their assets are being used.
