I am totally aware that there was another l e a k following the episode  *|_£-@!©'$* that included song related links. That includes instrumentals (Ah, those wonderful sounding musical tools sewn together to create and harmonious sounding pieces), vocal tracks (Ah, those wonderfully sounding vocals ... Brung together to make amazing sounding choirs), demos (Simple instrumentation (then full instrumentation) meets average vocalists(but i guess many actually include the two most prominent mane6 singers that aren't voice actors) equals raw, mediocre tracks), vocal sheets( FINALLY I CAN KNOW HOW TO SING THOSE DAMN HARMONIES ON A SONG WITHOUT SEPARATING IT FROM THE MAIN TRACK WHICH ISN'T ALWAYS POSSIBLE. But i dunno how to read musical notes. DAMNIT) and i guess some animatics which are kinda rare. Don't ask me on graphical matters. At all. 
Anyway i am fully aware of those, but it will take very long to retrieve a copy of them. Meanwhile, some of the channels i know have provided some of the instrumentals from those H A C K S . That includes El Brony Villero and Eddy Titron -(can't bother with the links, plz search urself)- actually you know what? I bothered with the links.

There may be others who also got those files. I think UploadCorner was one of them(i think you already know this one). It's probably around somewhere. I'll get to upload some (or even all.....) when i get these... if i ever get them.... see, this is the first time that i am downloading files across multiple days instead of within one day, and as such, is the first time im using torrents as opposed to direct downloads.... Also since when torrents are actually slower than direct downloads? And if i understand correctly, my upload speed is so trash that i rather not seed anything (it really isn't very suitable for live streaming. Just some video calls and small file uploads. Just your average stuff). (No wonder why the price for internets are so cheap here. Or maybe i am not aware if they offer an upload speed upgrade, since I'm not the one dealing with it. Nor the one dealing with it knows much either. I'll just stick to what i have. There.)
