I think maybe I read it on mj's blog, not TWoP...because I can't find it now. I don't blame you for not going to TWoP, though the Kris threads on mj's blog are pretty normal nowadays (if you can take the gushing about his hotness, which can get a little OTT).
So I went over to TWoP to try to find the post in question, and I see the person who calls him/herself FreeBallgamer (who seems to be the artist formerly known as Sweet and Sour, but who knows?) is up to the old tricks. I like to click on these people's names and bring up their old posts...back in October this person was saying people just didn't like LLWD. and wouldn't ever buy it. Now it's the same with the album. The comments are right on time since Kris/LLWD sold the most downloads of all the idols this week, and his album had a 34% (I think) increase in sales over last week.
There wasn't a lot of info, just that Kris went to say single and corrected himself and said song.
Do you know where you heard it? I think that's what we're trying to figure out.
Personally I think he just meant to say "song" and said "single." I say this without having heard him , so what do I know? Probably just a case of misspeaking that means nothing.
