I've never heard anyone talk about Crafton & Xunk before, and honestly, I don't even remember how I found out about it.
I do. 
The latter is a deal-breaker for me, since converters are fine and dandy, but I absolutely can't STAND when a game is played at a slower speed than intended -- especially the music! If I'm familiar with a game at all and notice the music playing slower than I know it's supposed to, I just immediately turn it off -- that's a great big "no thanks" for me! 
I hear ya, brother.
On my YouTube videos of soundtracks, I generally get two types of complaints:
(1) What a shame that you recorded this 60Hz music on 60Hz, when I grew up I played it on 50Hz
(2) What a shame that you recorded this 50Hz music on 50Hz, when I grew up I played it on 60Hz
Well, when I grew up, I initially didn't even have a colour TV. So by that logic, I should also upload everything in black and white then.

Oh, was it from you?

Hahah, the exact same complaints that my videos are getting. 
Nostalgia can be a bad thing sometimes.
By the way, Wyrdwad, I *love* your idea of making a buyer's guide video for the MSX. Once it's done, I wouldn't mind posting it also on my YouTube channel. With your permission and full crediting, of course.
