CD's are superior so I buy them when I get the itch to buy new music.
1) I can convert it into any digital format with my own decision on how much quality loss I will tollerate.
2) I can carry them into any car or house system no problem.
3) they only run $10 or less and generally I do enjoy the entire CD so little benefit for paying $1/song.
4) generally if I listen to things besides CD it's either internet radio or regular radio which is free.
