Should I be credited in writing credits if I re-wrote and re-recorded instruments for a song I didn't write originally ?
Self-explanatory. I'm mixing an instrumental for a singer I'm working with. She sent me the stems of all tracks for the instrumental, which was written by another guy. However some of the instruments were so badly recorded that I had to re-record guitar parts, synth parts, bass part....
I also added new parts, mainly guitars, that enhance the song. I presented it to the singer, and she agreed that it sounds better with what I added. However, I'm her mixing guy. I'm not sure if I should ask to credit me for songwriting on that specific song too. Since I decided on my own will to re-record and add new parts, I don't know where this falls morally. What would you do ?
