hey guys,
you're usually really good at this, i googled the line and i still can't find the song.

i heard it on the modern rock station in my city a couple of days ago. i'm quite positive that the song isn't by a local band. anyway,

the line that sticks in my head is: i want you to leave me

i don't know if that's the exact line, but i know it's close.

musically the vocal melody goes

e b a g# e f#

if you could help, that would be really awesome.
yeah, yeah, whatever
Is it "Keeper" by Yellowcard? That's what Google gave me and the melody is similar enough.

Hope it helps.

Btw, your username is awesome.
