The album covers are, for me, just an easy way to remember which album a song is on. Like someone's avatar on the forum. I see the avatar as a quick and easy way to see who's posting without reading the name. And that's kind of automatic. And there are certainly a lot of avatars on here that are worse than ADTOE's cover.
But, in reality, I think the covers do a good job at describing the music in the album. At least so far they have. Falling Into Infinity, I think, perfectly describes the song in it. Smooth, quiet, interesting.
Systematic Chaos is a pretty good cover for the songs. All of them, I think, are perfect for their songs. And I think this album will follow suit.
