well then the review should be titled "30 Seconds To Mars - This Is War (Leaked Version)" since that's what he heard and reviewed. it wouldn't be a big deal if a whole 1/5 of his review wasn't about a song that doesn't appear on the actual album.
The person that reviewed this album is a female. For someone that pays as close attention to details as yourself I'd think you would have noticed that. Also the aforementioned song with Kanye is on the album, simply without Kanye, dumbass.
