Why Does Samus Rock So Hard?

I've spent the past hour or so listening to mp3s downloaded from this site. And quite frankly, they kick some serious ass. Now all I want to do is play Metroid, but I don't have any roms, and my NES is in a state of non-hooked-upedness due to my lack of an RF Modulator. Seriously, though...This Metroid Metal thing kicks ass. Maybe Mikey is onto something afterall.
