Spotify compresses it anyway but for digital audio you'd want to encode in 48 kHZ/24 bit whereas CD only supports 44.1 kHZ/16 bit. Anyone who can hear the difference would be an exceptional listener with an exceptional sound system though, at least assuming the masters are generated with proper dithering.

We're getting our audio onto Spotify via CDBaby's distribution program, and they require 44.1 kHZ/16 bit.

(I initially tried uploading 24bit and they rejected it.)

Oh. Well, even more reason to make sure you use proper dithering.
