;D Thanks! I decided to sleep in today, so I didn't have to opportunity to do this myself yet.
I think that the funny thing is that Linus is actually a pretty decent rapper. Like, most amateurs on Soundcloud record in inadequate environments, don't keep constant volume or distance from the mic while singing, have terrible diction, and don't use pop filters (so all the plosives clip) - but with Linus' rap recording, none of these problems were present. The audio was actually really easy to work with.
EDIT: Also, thanks for your kind words, people!
