Hello, you do realize that it doesn't mean the thread author
has to be MIA, right?
I'm still alive and I will still answer questions the best I can and whenever I can. It just so happens that this thread has no activity.
Don't be like this.
Besides,
I borrowed the song from Mario Forever where it was labelled as
fastrun2.ogg
.
After some searching, turns out the song comes from a demo scene and it is named "Sirens".
You can listen to it here:
