Replying to Argh this is driving me insane!

So there is this song I've been hearing every-so often and I really want to find the title of it so I can obtain a copy of it for myself. Everyone I talk to whos knows which song I'm talking about either doesn't know the title or if they forgot what it was. So I'm trying my luck on here...

Ok, first off it has a violin that plays through the whole song, or well a sample of a violin anyway. It's a hip hop song and the vocals sound like the Swollen Members. Also some of the lyrics are "Don't hold back, World" or possibly "Don't look back, World". I'm not really sure it's been a few weeks since I've heard it but it's still kindah stuck in my head and I'm going nuts.

Any help would be greatly appreciated.
