Bassline Junkie lyrics are incorrect.

I was listening to the song Bassline Junkie by Dizzee rascal and I noticed that in the bassline bible it says 'I'm a bassline junkie' 4 times, but the lyrics are 'I'm a bassline junkie (what) I'm a bassline junkie (tell him again) I'm a bassline junkie (tell him again) and I like it funky' I wonder which is correct.
