I want to know the answer to the following question:
What kind of sound did Kanye abandon a rap and hiphop one for with his fourth album?
All the background I'm provided with is that "West's fourth studio album, 808s & Heartbreak (2008), marked an even more radical departure from his previous releases, largely abandoning rap and hip hop stylings in favor of a stark electropop sound composed of virtual synthesis, the Roland TR-808 drum machine, and explicitly auto-tuned vocal tracks.". Is that enough to answer the question?
Answer: yes
