Carrie Underwood will have many reasons to be happy come this week. Firstly, her third and new studio albumPlay On is expected to debut at #1 on the Billboard 200, making her do it for the second time, with a nice chunk of sales. But the other achievement the country star should be super excited about is that her current single "Cowboy Casanova" hit #1 on the country charts! This becomes her 8th #1 single on the chart! That is one more than Shania Twain has had on the US Country charts!

i am not 100% this is accurate but I guess someone will know.
