Kind Of BlueMiles Davis
Forget for a moment that the Wikipedia article says "Kind of Blue has been regarded by many critics as the greatest jazz record, Davis's masterpiece, and one of the best albums of all time." This is music we have heard our whole lives. There is clearly a reason for this. This is music that is composed, not just a jam session. This is technical art. You can either listen intently or just have it playing in the background. This is an album that has been STUDIED for decades. In the end, your opinion of whether you like it or not is completely irrelevant.
