I noticed this as well but the mix sounds great so I'm ok with it. Billy's bass sounds the best I've ever heard it. For a rock album, the 5 1 is really really good. Excellent fidelity and some nice panning effects when the opportunity presents itself. I heartily recommend this title if you like the music. I would buy up every 80's/90's rock surround release if they sounded like this.
100% agree with this. That said, I did lower the centre channel just a wee bit. Sounds a bit more balanced to my ear now.
