The layout and design is a matter of taste. I actually find websites like OP refreshing to see.

Blasting music or sound on auto play when you aren't directly navigating to audio or video content is just rude.

It's the same as playing your speaker on the subway.

This is my problem with it. Put in a mute button if you're going to do this, otherwise it's just user hostile. No problem with stylized websites and fun animations.
