Does album artwork actually matter now?

With the increase of the digital download of music and use of sources such as Spotify, I find myself less and less looking at the actual album sleeve. With this said, does album artwork really matter any more?. years past I remember going into record shops and looking through the collection of CDs there and seeing what catches my eye, however now im a heavy user of Spotify so now I just search for the music I want and listen to it without looking at anything else. I think it has something to do with what kind of music is on the market today. A lot of the current popular pop artists release songs written for them on digital download services such as iTunes all to make a quick profit for the record companies without the need for money to be spent on things such as album sleeves. Below are some examples of album art released in 2013

As you can see theres not much in the way of creativity with these examples, however they have all gone on to sell millions. Now looking back at older album covers by bands such as Rage Against The Machine or Frank Zappa (examples below) they are much more striking. hwoever the music is alot different.

So does the music style dictate what kind of album artwork there should be? With the Rage against the machines album where the monk is on fire (a political protest that happened in Saigon) every song on the album has a political message as a result the controversial cover art is relevant. Pop artist that have most of there songs written for them and contain little of any emotional or political context, coupled with having nothing special for cover art they still sell very well. Albums that have different messages in the songs and artwork worth looking at sell the same. 

I don't see how artwork matters any more in today's current market.
