the song writer
She co-writes all of her songs. Which means that the REAL song writer agrees to let Katy change a couple of words in a song so that Katy can get credit for writing the song to make her seem like a real musical artist instead of a just a singer.
Which musical? In general, the term is "librettist" for the guy who writes the music and "lyricist" for the guy who writes the lyrics (words).
The lyricist (writer of the words) and the score-composer (writer of the musical notes) are the song co-authors. The singer does not get credit for being the author of the song unless he has contributed words or music to the composition.
A composer.
A person that writes a song.
The composer or arranger.
Yes, leave the song writing to the professionals. When an amateur writes a song they most often get taking to court. BEWARE!
