I want to know the answer to the following question:
How many total CDs has Kanye West released in his career so far?
All the background I'm provided with is that "He went on to explore a variety of different musical styles on subsequent albums that included the baroque-inflected Late Registration (2005), the arena-inspired Graduation (2007), and the starkly polarizing 808s & Heartbreak (2008).". Is that enough to answer the question?
