I really like the song and even though I'd probably go out and buy the album, I think they've done music similar to this that have been a lot better. The album Sabotage the song "Megalomania" sorta sounds similar to this but in my opinion the older song is better:
Edit: Also, i'm not feeling the drums a lot, and it's funny because you wouldn't think BS and think about their drummer. However, Bill Ward is great and I can really hear the absence of the BS sound without him... sorta incomplete?
Edit 2: Listened to it again, it's definitely the drums that are lacking.
