How should I decorate my room for Halloween?

Hi, I am wondering how I should decorate my room for Halloween. I am being a genie, and I am wondering if this should affect my room decorating? I like pink a LOT, but I also heart black. I want to do it in the cheapest way possible, too. I'm fine with handling live spiders, and cobwebs. I also love the genres of music, these ones: Pop, rock, soul, hip hop, and R&B. I am OBSESSED with Avril Lavigne and Pink. Hope this information helps! So PLEASE help!
