Pigstep is OK, because the music disks were a bit oddball anyway, but I really don't like the non-c418 in game music. They feel out of place.
It also an issue that the reason c418 didn't get to keep doing the Minecraft music, was that he refused to do it on "work for hire, sign over all the rights" terms.
I'm quite certain there's a mod to manage your in-game playlists, and unlike in e.g. Factorio, the server doesn't even need to know about it.
As for c418, you're privileged as an artist when you get to keep your rights and make decent money. That was a very smart strategic move. Microsoft could've responded in any number of ways, but keeping the music + hiring new artists doesn't even sound like a bad compromise; these artists deserve the exposure, even if they can't match c418.
Yeah I like Lena but nobody was going to live up to the bar C418 set unless it was just ripping off of him entirely. Maybe if they got Brian Eno. But how many tracks are you going to get him to do for a videogame?
