I played this on my classic nylon stringed acoustic guitar and it sounds right, however B plays it on a steel stringed acoustic. I tried some other tabs, guitar pro and chords but they were wrong or didn't quite sound so i listened to the song and slowly did this. Play this riff through the whole song and you're done (the chords are Em and E) Plan B plays really loudly at the beginning and plays it quietly when he's He also plays very quickly when he says 'you better think twice, before you step to me and pick a at the end of the song.
