The very first time I listened to it, I wasn't paying much attention to it. Around the 3rd track, I thought "meh, might as well put on something I'll pay attention to". It was then I realized how amazing the currently playing riff was, so I left it on. This happened 3-4 more times in the first listen. I was totally unable to turn it off, even after deciding I wasn't in the right mood and wasn't paying any attention. Since then, it's grown on me more and more, but yeah, it's one of those albums I've recognized the brilliance of from the very first listen.
