That's quite interesting, I just read several articles related to it. Methane seems like it would be quite abundant, since it is Carbon and Hydrogen, which are very readily available in the universe.
I think we might be really reaching the limits of our current technology with this find. I feel that the only reason this was discovered is because of how hot the planet is. I couldn't find any technical articles, but usually compounds such as this are found because of their emission line spectrum - and that would only have been visible because of the heat there.
It's not inconceivable that life would be there. It's cold conditions that really slow down the chemical processes that lead to life, so if this temperature is within the threshold of chemical reaction performance, then there could be life.
Something else to consider is that nearly every planet in our solar system has methane, and several have water in some form. That means that there could be other planets closer towards the "green zone" of this alien sun which would be perfect for life. It would be incredibly hard to detect a planet there, and even harder (if not impossible) to determine its chemical make-up, but I'm glad astronomers aren't just sitting on their hands.
