Very true, but either way I feel like Dr. Luke and Gaga just wouldn't work. Look at his past catalogue and the amount of work the artist contributes vs. what Gaga does. I don't know how he'd fare with a true musician.
I don't think she should ever lower herself to Dr. Luke. Some of his songs are brilliant, but he is undoubtedly the go-to-guy for someone who wants a hit. Gaga likes to create all her own music.
