The problem is that 90% of their 2 mil song catalog is still only CD Quality (16 bit / 44.1 Khz). 256 / 320 Kbps vs. CD Quality is pretty hard to differentiate

The problem is that 90% of their 2 mil song catalog is still only CD Quality (16 bit / 44.1 Khz). 256 / 320 Kbps vs. CD Quality is pretty hard to differentiate for most people. But 256 / 320 Kbps vs. 24 bit / 96 Khz should be fairly obvious. And of course, you need a good pair of headphones.
