I still say there is nothing better than driving down the road with the windows down and hearing a song you haven't heard in ages come on the radio (in this case now - satellite). No matter how many songs you put on an mp3 or onto a CD that's burned you still pick them or will hear them played again. I'd miss the laugh or smile that came to my face when the first few notes of a song I haven't heard in ages takes me back to a story or event I forgot about growing up (its not a long time I'm only 34).
Then I turn up the volume, sing along as loud as I can, shake my head and hope I'll hear it again sometime down the road. No burned CD or mp3 that I make can do that.
