People have different views on Marilyn Manson, I like some of his songs, others don't.
In terms of his music, I guess the only one real thing that sticks out, is his singing. Manson's voice, to me, is just very raw and very energetic. The emotion to it just sounds fake and feigned. Manson's vocals are not the loudest, but they do sound genuine. In terms of his music, though, it's funny that most of my favorite songs he's done are covers, like Sweet Dreams.
