Firework and Seek (Imogen Heap x Katy Perry)

NO COPYRIGHT INFRINGEMENT INTENDED. ALL AUDIO BELONGS TO THE ARTISTS AND THIER RESPECTIVE RECORD COMPANIES. That being said, here's a mashup I did (using DJay) of Firework by Katy Perry, and Hide and Seek (Otto Knows Remix) by Imogen Heap. Looking for some honest feedback. Tell me what you think. Thanks!
