Excellent points, klodolph, and I'd add is that he used 128K MP3, which is well known to not be as good as CD quality. Most music services use 320K MP3 these days when bandwidth isn't an issue (e.g. over wifi).
Hey, as I mentioned in my response to klodolph, I used 128 CBR because I knew it would likely not be transparent and wanted to demonstrate false positives, hits, misses, correct recognitions, etc. I wasn't trying to make some authoritative critique of MP3 just because it's low settings are indeed low quality.
