What makes a great album? There is no one thing that makes an album "great". Is it the quality of the music? The talent of the musicians? Sometimes, but some of my favorite albums were made by bands who were not what you would call "great musicians". The Misfits or The Ramones come to mind. Is it lyrical content? Again, sometimes but not necessarily. A song need not contain flowery prose or well executed poetry to make it great. So, what is it then? Art appreciation (and music, even metal, is certainly an art form) is subjective, to say the least.
