Deleting Purchased Songs etc. (as though I'd never bought them)

Hi,

One cold Christmas, a long time ago, when iPhones and apps were a new thing, iTunes released an Xmas app giving away free games, music and videos everyday of the 12 days of Xmas.

This was great! The problem was I thought I had to download the freebie whether I wanted it or not to get the next one the following day. This obviously wasn't the case.

I downloaded a few things I still like today but really doesn't look good for my credibility when people see Leona Lewis, Robbie Williams and Duran Duran music tracks... Not to mention when my in-laws see I've got the Lesbian Vampire Killers movie.

I've managed to delete these from my phone but they still show up in the cloud ready to download. I want them completely removed as though I've never even downloaded them... Almost like that sweater I received that Xmas, I returned it to the store because I'd never wear it. Now no one can even see it hanging in my wardrobe.

Thanks for your help,

Steve
