Cover art for Killed By An Angel lyrics by Sunny Day Real Estate

Wow, this is a really great song... I'm assuming it's about hallucinogens. He's talking about "breaking your day for pay and ration, hide hide hide" as in hiding from the daily pains by using drugs. Other things like "lost inside amazing colors," "it comes in a bottle," and "a hole in your brain" are obvious references to being high. I like the line "It's cold when you remove the nails," referring to withdrawal. Great song, very good.
