7digital is a veteran of DRM-free MP3s. They sell Graduation in 320kbps MP3 format (the golden standard for MP3 users). You get a clean zip file upon purchase.
First, let’s address the “High Quality” part of your search query. Graduation is not an album you want to experience through 128kbps YouTube rips. This record is a sonic tapestry.
Believe it or not, Amazon still sells MP3s. When you buy Graduation on Amazon, you can download the entire album as a zip folder via the “Amazon Music for PC” app, then move the files to any device.
