Utter shite mate.

MP3s can be far far superior to vinyl in terms of audio fidelity.
Low bitrate mp3s sound poor, high bitrate are indistinguishable from WAVs.

Why as a producer and an audio engineer would you want your music to be carved into a piece of plastic and played and amplified through a vibrating stylus?

320kbps is as good as a WAV, smaller and easier to store and indentify with tags.
WAV is the way it will ultimately go (hopefully 24bit96khz as well), but in the mean time upwards of 256kbps mp3s are fine and dandy.
