Should truly fresh steak (i. e. still purple) have a smell? I recently purchased a strip steak from my local grocery.  Got home and noticed that the other side (the side that was face down at the deli) had a section that was noticeably purple.  If I get really close, there is definitely a smell, but it's not a great smell.  I've smelled oxidized (brown) beef before and find it has kind of a "sweet" smell, but this is not that.  

My first thought was that I was sold spoiled steak.  Then I cut the steak in half and noticed that the inside of the steak was the same color and had the same smell.  I don't think steak spoils from the inside out, so now I don't know.

For what it's worth, it's the smell that's got me concerned.  There's no other signs of spoilage that I can find--the steak isn't sticky or slimy.

Can anyone provide some expert advice on this?  I'm inclined to think it's fine and is just really, REALLY fresh, but I'm hoping someone else knows what's going on.
I ate the steak and was fine.  I think it was just an non-oxidized portion of steak.  I let it sit in the refrigerator for an hour or so before it I ate it and it's color changed from purple to red, so I'm inclined to think oxidation.
