Before the emergence of digital music, album covers were an integral part of music buying. I can recall spending time thumbing through the record racks, looking for eye-catching album covers that would sometimes play a deciding factor on whether or not I would purchase it. The art was usually very creative and super cool to look at. Many of the album covers have become classics, such as the Beatles Sgt. Pepper's Lonely Hearts Club Band and Led Zeppelin's Houses of the Holy to name a few.
