You do realise that Bjork and her producers have access to the best professional music software on the planet right? The music production capabilities of Dreams can't match FL Studio's base $80 package. The production software she uses is so far beyond what Dreams is capable of it's laughable to imagine she or anyone around her would even consider it. You might as well ask Stephen Spielberg to film his next summer blockbuster with an Iphone.
that's wrong in so many levels, that i don't even know where to start, first of all if we are talking about bjork - human behavior tune it's mainly composed with live instruments, second of all the tune was released in 1993, software at that time was pretty primitive, also you needed additional hardware to even record a 8 track. Hardware tools dominated back then like synths, samplers, sequencers and tape/adat machines. So software wise Dreams is wayyyyy more advanced than what they had back then. It's not about tools, it's about a person that makes the music.

Yes, she went to bigger studios eventually to record stuff she needed, but with the tools that Dreams has, you can make a tune at a similar level if you know what you are doing.
