Album Covers.

Album covers. 

Fantastic Five:

Some album covers are meant to grab the attention of your eye by jumping out to a specific type of person, or type of genre you like. Some covers can give you an idea of the kind of music that is in the album, the general feel of the music itself, or the artists that made the music. Either way, the design is to catch your eye, and help persuade you to buy it. 

For example, Iron Maiden's The Number of the Beast album generated huge sales, and inspired a lot of up and coming metal musicians. The general idea is to show you exactly what your getting with the album right on the cover with all the colors, and the devil, along with the Maiden. 

Obviously that's a finger, but at first glance in a store, this is more than likely to make you do a double take at it, and be a little curious. 

This is obviously a statement about the music you will find in the album. The artists probably wanted to say right away by looking at the cover that this was going to be a powerful album. 

This also is a statement about the album. This group believes the music in this album, is they're greatest hits, and associates that with a hard hit in boxing. 

Not every artist uses this form of album to sell they're products, but it does seem to help catch your eye.
