as long as they are listening to it on the same system...hopefully a decent one, there should be no problem.
That's true. It's like anything else though, it's just a matter of training. If you know what to listen for, particularly with material you're very familiar with, it shouldn't be that hard to notice the differences.
My guess would be if you took 100 people (general audience, not musically trained) all listening to the exact same song on the exact same setup, one is the MP3, one is the WAV (and assuming they didn't even know if there's difference between the two clips they were listening to), the majority would not even hear a difference at all.
Now if you told a group of 100 musicians (one's with "good" ears, haha) that one of these clips is an MP3, and one is a WAV, and pick which one you think is the better one. You might get half picking the WAV, and half picking an MP3. I'm just theorizing here, nothing to back this up.
These compressions schemes are definetly getting better all the time though, I'll give them that. Doing a direct A/B comparison with music I know, I've been able to tell a difference, but I think that's getting harder and harder as the technology gets better.
I'll sum up by saying: MP3s are bad on principal. I need those "extra" bits to be happy
