If you look in the songs chart thread, there is about 20 or 30 pages on this very issue, with many upset people, including me. lol
I tweeted Tony Thomas of KMPS Seattle, and also Bobby Bare from 93 Fm, and they both wrote back, saying PO is done. they said no more singles. I am very upset about it too. Tony Thomas did say he believes Carrie's next single is coming off a new album, but he didn't say it would be Carrie's new album. He kind of hinted that it would come off of a new album of some other artist. So this could mean a duet on someone else's album will be the next single. I really wanted SWISLY though.
I hope they have something special planned, like a collaboration with someone or a duet.
Carrie did blog and post several times that she did some special recordings we won't get to hear until 2011. She also recently posted on the FC that she did not do a duet with Kelly Clarkson, but she did do some collabs with other people, and is planning to do more collabs with others this year.
So my best guess, is that the next radio single will be a special surprise with a duet with someone, hopefully hitting radio soon. I just hope we don't have to wait too much longer to find out or I will die of waitiing. lol
