I like Jarrett's as much as I can like a ripoff of Triple H's 'My Time' theme.
TNA can do a lot better, in my opinion, but Oliver probably comes cheap or has a buddy there. He's had some good ones, but I'd say 95% of his work is only ripping off something else, whether it's a real song or that wrestler's past WWE theme, and even most of his good songs are still ripping off something else. They all have this similar feel or quality to them, really cheap and amateurish, honestly, almost tin like, if I had to describe it. I'd be surprised to learn that he uses more than two guitars, more than one set of drums in his work, for example, or rather, if he even knows how to use things like Pro Tools and mixing boards. Maybe he just sits at either in befuddlement.
