You can't tell with like apple earbuds that much but if you have nice headphones the quality is very distinctly different. There is a good amount of static all throughout the bad one, like a lot. I didn't like the song at first because I got all ready for it with my nice headphones and I first heard it like that and was like "whattttt

". Hearing the clean version was like a new experience and I'm so mad that iTunes could **** up that much.
Blue Velvet I don't have a problem with. Apparently Burning Desire also has the problem but I haven't heard it yet as I was waiting to hear everything once the EP is out...
