Yes, but I would assume any Anthrax fan would have listened to it.
As far as album sales are concerned, how can anyone say what one factor played the biggest part? Did the change in musical direction alienate many long-time fans and turn them off? Yes, without question. Was that the only factor? Not by a long shot. Sound of White Noise did very well, even with Only being on the record. Anthrax had zero label support after that album.
Every single label they've been with since Elektra is now out of business. Are you going to lay all that at Anthrax's feet? Don't you think the poor luck with labels may have played a part with poor album sales? Speaking for myself, I never realized there was an album called Volume 8 until years after the fact. I'm just saying it took more than what some people here consider bad music to bring down album sales.
