Another question: several times in the article I have seen sentences like this: 

 *The album was reported to have sold in 90,000 copies. 

 I thought the word "in" sounded odd, so I've been removing it so that the sentence reads: 

 *The album was reported to have sold 90,000 copies. 

 Then I thought, well, the album doesn't actually sell anything (transitive verb). So now I don't know what's correct. I suppose passive voice could be used: 

 *90,000 copies of the album have been sold. 

 What do you recommend?
