This is slightly old but I haven't heared them mentioned on these forums besides iBall sometimes posting some of their lyrics.
Basically the Futuristic Sex Robots have an album called Hotel Coral Essex. It falls under the weird genre of Gangsta Nerd Rap. You may think that sounds crap, and I did at first, especially since I normally don't listen to any rap music. However the nerdiness shines through and it actually sounds good!
If you are a nerd, or enjoyed songs like Weird Al's 'White and Nerdy' then you should give this album a listen. It's free and the lyrics are hillarious.
