nn Interesting how they didn't mention Gaga, where she wins with everything. Who had the freshest sound in 2008, 2009, 2010 and 2011 ? Gaga. Who has bigger fanbase and bigger connection with her fans ? Gaga.
And Beyonce had released Sasha and 4 - pretty cohesive albums.
And Taylor has bigger connection with her fans, hence the success.
Katy has some great hits and sometimes she isn't given enough credit, but yeah she is not making it easy on herself.
