There is something in an album cover...

There is something in an album cover that either interests me or doesn't. I believe that covers are the forgotten elements in regards to releases these days. I think that a classic album should be classic in every way, shape or form. The music has to be good and the artwork must be inviting. The artwork should sum up the direction of the album. I also believe that classic album covers do not have to be too complex. What are some of your favorite album covers of all-time?
