I think it is pretty good. The songs seem to be hit or miss with me so far though. Either I think they are really sick or I don't like them at all. I got the DualDisk version in the used bin (still in the wrapper though) at a shop here in Seattle for $7.99...so I really can't complain.
I would give it a 6.5 maybe a 7/10 as of right now.
