Personally I will listen to almost anything myself!!
Current favourite tunes consist of a touch of R&B - R.Kelly & Joe in particular!!
If you must drive fast then anything with a decent beat, such as Dance / Trance is great also - just keep an eye on the speedo!! LOL -

P.S - I echo Skiptons comments - take the plunge - the A2 is a current / future classic that ticks all the boxes - cheap to run, fun to drive, possesses ingenious design features and has that all important Audi badge!!
Personally, I like Vision Creation Newsun by Boredoms. Seriously good driving music, just keep an eye on the speedo! Recently been revisiting an old favourite: IMA by BT. Dance music is usually good for driving I find.
