Katy Perry is mad at me

EMI Records and Katy Perry have contacted Soundcloud. And my mashup using the instrumental for Hot n Cold has been been taken down from Soundcloud. I think it is sad when artists don't appreciate the free advertisement they get from mashups. My mashups would never in any way inflight on Katy Perry's record sales. I have to respect Katy Perrys/Emi:s wish and will not upload that track again. Congratulations you all who have allready donwloaded it! Here is the mail I got (I migh add that if soundcloud didn't host barely illegal stuff, they'd probably be nowhere near the revenue they have today):
