I drove to work at 7 AM yesterday and "3" was the last song I heard before I got out of my car. I got off at 4 and it was on again when I got in my car. KIIS is playing it like crazy.
I think 3's sales have a chance to be huge and put Britney at #1. I think since this song is so catchy and many people seem to love it, and not many people outside of big britney fans will buy the The Singles Collection, it will cause people to stick with just buying this brand new song because that is the only way they can get it without buying a whole singles collection. I think that may lead to "3" being able to Debut at #1, not to mention it just came out so you know there is going to be alot of online streaming going on, and her radio play so far has not been bad at all. I don't know much about radio play but I would say her aud. will be atleast 20 million. I could be wrong but that is just what i was thinking.
