By the Grace of God is an Adult Contemporary Christian song that has received one performance. It is not on radio, it doesn't have a video. It is not getting the single treatment. Prism sold well in the US with just 2 hits. 1.5 million US and 3.4 million worldwide is not bad at all. I'm not sure which top 10 you're referring to but all 3 of Katy's albums were in the top 20 on iTunes BEFORE her performance. Prism went up to #4. Anymore questions? I'll wait for one of the LittleSuicides to answer mine though.
