I see no problem with making someone write a piece in five days... in fact, these things should only give you a week honestly. Anyone who needs more needs to either learn to use their DAW correctly or move to Hollywood already because the stuff they're making is so perfectly produced. XD
I'm rather skeptical on the whole Nortte thing... I believe that someone either set it up (i.e. hacked his account and changed the uploaded file without him knowing) or the xm project was stolen from him at some point during assembly and some jealous competitor decided it would be a fun joke.
Also, I believe it is his birthday (at least on skype)... maybe someone who knows how to hack things wanted to play a Birthday prank.
If he did steal it, then I'll be darned... never expected that... but I guess I'll never learn his amazing flute tricks he did in the works I KNOW he did.
