[Intro: soft keys, finger snaps, vocal ad-libs] (Yeah… uh-huh) (Whenever you need me, girl) [Verse 1: Rap — laid-back, conversational flow] Pull up on your block when the streetlights glow, Candy paint drippin' slow, radio low. Ain't no static on my line, I keep it clear for you, Say the word and I'm through, that's what I'm here to do. You been holdin' it down since the summertime, Got your name in my phone with a heart beside. Don't matter where I'm at — studio, out of state, I'll be pullin' out the lot 'fore you can hesitate. So if the world get heavy and it press on you, Just tap that little screen, I know exactly what to do. Ain't gotta text me twice, ain't gotta beg or plead, 'Cause you the only number that I keep on speed. [Pre-Chorus: half-sung, building] No matter what time, day or night, Rain or shine, wrong or right — Ain't no signal ever drop on you… [Chorus: Sung — smooth R&B, layered harmonies] I'm on your speed dial, baby, just say when, One little ring and I'm right back again. Don't matter the hour, don't matter the mile, I'm one number down on your speed dial. (Just say when, girl) One little ring and I'm right back again, Never let it ring out, never let it go, I'm one number down, and you already know. [Verse 2: Rap — slightly more animated] Uh, I keep it charged up, ninety-nine percent, Never miss a call, that's how the story went. You could catch me in the mix, catch me in the crowd, Still hear your ringtone if the room too loud. Ain't no "can't talk now," ain't no "hit me later," Ain't no shorty on my hip playin' navigator. Real one on the line, keep the volume high, You could send a single word and I'm outside. Two in the mornin', you can't sleep at all? I'm already up, girl, take the call. Bad day at the crib, need a place to hide? Say the address one time, and I'm on my way. [Chorus: Sung] I'm on your speed dial, baby, just say when, One little ring and I'm right back again. Don't matter the hour, don't matter the mile, I'm one number down on your speed dial. (Just say when, girl) One little ring and I'm right back again, Never let it ring out, never let it go, I'm one number down, and you already know. [Bridge: Sung — stripped back, minimal drums] Some people talk loud but they never show, I'ma stay the same when the cameras go. Save me at the top, don't scroll too far, Wherever you are… wherever you are… (I'm there, I'm there) [Chorus: Sung — full harmonies, ad-libs] I'm on your speed dial, baby, just say when, One little ring and I'm right back again. Don't matter the hour, don't matter the mile, I'm one number down on your speed dial. [Outro: fading ad-libs over keys] (Speed dial… yeah) (One ring, that's all) (I got you, girl… I got you)
