Not exactly the appropriate demographic at all.
But if you want the opinion of someone who's watched way weirder stuff out of Japan than this (search Nekokiru-so on YouTube if you want a weird, beautiful, mind-numbing movie from Japan sans tentacle porn...) the animation is haphazard, and the video isn't well-timed in most places. This borders on disgusting more than just creepy, and hardly beautiful!
But I'm the opposite of most Chazzers and have seen way too much of this stuff. Just seems weird to use animation like this for a music video unless you're intent on alienating a lot of your fans.
Also, this:
A lot of adult animation is incredible, beautiful, and amazing story-wise. You're missing out on a lot of great animation from all cultures if you limit yourself to the American ideal of "cartoons = for kids"
It's not just Japan, either. If you haven't seen
Les Triplettes De Belleville (SFW)...
