Paying per track == stupidity (Score 1)

How can anyone say that they would pay per track, I mean is ridiculous. This means if you were willing to pay 25 cents a track you would only have to pay $1.25 for Chemical Brothers 'Brothers Gonna Work it Out, but if you wanted to buy White Stripes 'White Blood Cells' I'd have to pay $4.00. The thing is The Chemical Brothers albulm is longer. There is no way music industry could have a flat rate, the price of the track would have to be based on the length of the song.
