I really like Aenima, but it's all like a big blur for me.
Personally I think the 'style' or whatever that Tool had on that album, I feel like the vocals got pretty drowned in the mix, and that as a whole, it was pretty hard to distinguish certain sounds over each other, it all blended together very good.
Another thing, there aren't really any songs on Aenima that stands out to me.
Yeah, songs like Eulogy and the title-track are great, but all my favorite are placed on Lateralus or 10k Days.
