But that's a relatively easy thing for a human with the right combination of toolchain, ears, and experience to fix. It tends to be a slow process that takes a good bit of time, but lots of actual-mixdowns start off way worse than this before they get polished up by a skilled mastering engineer.
(Maybe in a year or three we'll have the mastering process automated into an uncanny mush of soullessness, as well.)
Audio mastering is already automated to the level of a mediocre human:

(I haven't actually tried this, I just watched the linked Benn Jordan video.)
IMO, the ideal would be for all music to be supplied unmastered so the listener's playback software can apply this process to their own taste. Mastering is necessary for listening with garbage playback equipment (e.g. phone speakers) or noisy listening environments (e.g. cars, parties), but it makes things sound worse in good conditions. The best sounding music CDs I own are classical CDs on Telarc that have liner notes bragging about the complete lack of mastering.
