I just hook my iTrip up, set my ipod to shuffle randomly through all the songs, and play it through my stereo at full blast lol.

I once had a 4800 song marathon... Since I have like 50 days of straight music, I decided to start playing and just mark some of the good songs and what number they are... kind of like a countdown.. only a countUP. But then I allowed the battery on the ipod to die like an idiot so somewhere around 3000 straight songs the marathon ended.. such a stoner ending lol.
