In the past, I've written my songs and then asked friends if they could record the vocals. I didn't want to use my own voice, because other people have much better voices. I was hearing the music with a voice that I don't have. It was a case of pulling whatever resources I had to get the sound I wanted, but that doesn't take anything away from the authorship. They are songs written by me that sound the way I want them to sound. Whether it's my voice or someone else's doesn't make a difference to the music.
