Music? Ha! Speakers aren't just for music. Speakers are for movies, and television, and talk radio, and that recording your brother made back in 1993 when he got drunk for the first time. Isn't it worth seeing him cringe in true stereo?
You might have the best sounding sound in the world, but if you don't have speakers? NOTHING. NOTHING AT ALL. Let's face it, speakers are the vital link between "recording" and "ears" and don't get cute about headphones because they're just tiny speakers you wear on your head, and anyway, you can't wear headphones at a house party. That would just be rude. So speakers are the way to go. Trust us.
