I don't think Itunes can overtake the compact disc, theres just isn't any way, over 70% of the time i listen to music is in my car, as i have a cd player you can plug mp3 players into, i dont have an Ipod, and wene i plug my psp up to it it doesnt sound all that great, seeing as how alot of people listen to there music in a vehichle, and some people dont even have the internet, i would say it is well worth going to the local cd store and grabbing a cd off the shelf, well after i think about it memory cards have the potential to clean cds off the shelves, but it would probably raise the price of music.
