it'll use less power

cd player will always be quieter than a computer. if you have open phones it's actually a nice improvement... but then you have to start soundproofing your room, wishing you had a button to make all outside activity stop so you can have silence
maybe not true sonic improvements, but notable points at least. it's hard to appreciate true black silence when there's always some motor noise from the computer in the background.
my cd player sleeps next to me in my bed, I can't say that the computer would make a nice bedfellow in comparison, always snoring!
