There is no musicianship behind pop music. Period.
Comparing Lady Gaga to some of the greatest musicians who ever lived is like trying to compare a children's book to a novel.
Sure, a children's book might sell millions of copies. Sure, the author is technically an author.
But a children's book doesn't stack up to a Stephen King novel when you're talking about intricate masterpieces.
Gaga's music is the same old, machine processed garbage.
She wrote it. Good for her. Doesn't make her music unique, intricate, or interesting.
Anyone who likes Gaga or most pop music in general is a zombie.
