If I know the song or get used to it I start humming along and I lose concentration so. off!!!
Well I would love some Rancid in GT series I loved 'Out of Control' in NFS:U and that is sometimes the only track enabled...
(In case you are wondering why I play NFS:U; I have a PC so no GT3, I think its a decent game and my cars are sleepers)
But then I really lose control over my driving cause that song drives all my blood into my brain or something....
