Great choices! Really pleased that Machaut in particular has made it in; I wouldn't have expected any medieval music.
However, Henry VIII by Morse is obviously a misattribution, since I'm pretty sure Morse wasn't famous for painting Henry VIII - and we already know that Holbein's Henry VIII is going to be added. I hope this kind of thing won't happen in-game - it's pretty immersion-breaking.
Seriously? People will actually pay attention to this stuff?? They are simply bonuses to add to available slots, assuming that one would even care to get such bonuses.
