I just listened to it and honestly I think it's about agony. I love the song, I've listened to it hundreds of times - I just wanted a fresh go - I never really thought about it but it seems like he may have been suicidal or in a deep depression - just what I think :)

Here's a good link for some info... http://en.wikipedia.org/wiki/Add_It_Up Here's the lyrics any way... [a capella] Day after day I will walk and I will play But the day after today I will stop and I will start Why can't I get just one kiss? Why can't I get just one kiss? Believe me there's some things that I wouldn't miss But I look at your pants and <gasp> I need a kiss! Why can't I get just one screw? Why can't I get just one screw? Believe me I know what to do! But something won't let me make love to you. Why can't I get just one fuck? Why can't I get just one fuck? I guess it's got something to do with luck! But I waited my whole life for just one... Day after day I get angry And I will say That the day Is in my sight When I'll take a bow and say goodnight. Oh my my mymymy mo mo mum Have you kept your eye, your eye on your son? I know you've had problems You're not the only one When your sugar left, he left you on the run. Oh my my mymymy mo mo mum Take a look now at what your boy has done He's walkin' around like he's #1 He went downtown and he got him a gun. So don't shoot shoot shoot that thing at me Don't shoot shoot shoot that thing at me You know you've got my sympathy But don't shoot shoot shoot that thing at me [repeat] Broken down kitchen at the top of the stairs Can I mix in with your affairs? Share a smoke, make a joke Grasp and reach for a leg of hope. Words to memorize Words hypnotize Words make my mouth exercise Words all fail the magic prize Nothin' I can say when I'm in your thighs Mo my my mymymy mo my mother I would love to love you, lover City is restless, it's ready to pounce Here in your bedroom, ounce for ounce [repeat] I'm givin' you decision to make Things to lose, things to take Just as he's about ready to cut it up She said, "Wait a minute, honey, I'm gonna Add it up." Oh Add it up! Add it up! Add it up! Add it up! [repeat] Day after day I get angry And I will say That the day Is within my sight When I'll take a bow And say goodnight goodnight
