I'm just going to roundly disagree with Mr Young there.
Yes MP3 can be atrocious or actually pretty decent depending on how the compression is set up.
Use to be a little bit of a HiFi nut, so we did some experiments. A friend of mine had a really nice recording on CD that we used as reference, then we ripped it, and compressed it in various compression rates and did A-B blind comparison.
128k was pretty terrible
196k was noticeably better, on some poorer speakers 196k was almost indistinguishable from the original (due to lack of fidelity in the mid/highs), but on good speakers still sounded bad when you heard the A-B.
256k better again
320k was still perceptibly different if you knew what to listen for (weird HF scrambling)
320k VBR you'd really have to listen hard (make it up?) to tell the difference. We decided that 320k VBR was "acceptable".
What makes or breaks a recording though is the final studio down mix, and what its targeted for, most "pop" (aka garbage) is (or at least used to be) down mixed to sound good on crappy stereos, usually a bit of boost in the lows and some in the highs, and fairly compressed (ie dynamic range, not data) to overcome the short comings of the average radio. Put such a recording on a good system and it just sounds bad, quite tiring to listen to, wallowy bass and over done highs with no dynamics.
