I recently made a song And even wrote a lyric for it also i arrange it with fl studio And gave it to a singer.But as the song that I've arrange In terms of quality And type of Musical instrument chosen was poor Another composer as it arrange professional Now I have a question that is what my name should be on the album:Composer or arrangement or arrange with software And that after the song made by a professional composer The Smallest change in starting, expanding, and the end of the song was not given and Only instruments and effects to change And rhythms have been better. now can i name it (professional composer) as a Remix or cover to bring.(Forgive my language is not good) Thanks
