The problem I have with ghostwriter claims is that there is no proof at all. Anyone can claim to write your songs and it's really just their word vs the artist's word. People won't believe Drake has a ghostwriter because they like him. They'll believe Iggy does because they dont like her. People claim TI wrote Fancy then someone else claimed to write it. There is no consistency. Plus if TI wrote it, no one would be calling it trash because he's a damn good rapper. People believe what they want to.
