I definitely can't argue with that. I'm just making a point that this isn't the same as if, say, Jesus Piece had sold only 10K first week. It's not quite like an actual album, even though it is. But like you said, these numbers aren't good for any well-established artist.
To bring up a similar situation, I'd be more worried if I was B.o.B. who sold like 40K in his first week with a full-blown album, rather than Game selling 10K with a pretty-much compilation album.
