In my pop music today, you need to be constantly putting out new music or else you may become irrelevant. Katy Perry and Rihanna are prime examples. That is why I feared Lady Gaga took too long of a hiatus - first with a long tour for "Born This Way" and then her injury. Regardless, Gaga is back and has released her new single "Applause." When I first heard the song, I happened to be listening to it on the bus and I wasn't feeling it.
Then, when I heard it in a more normal setting, I realized how great the song is. It is upbeat, dancey, and New Wave-ish. Best part, Madonna cannot claim that Lady Gaga is mimicking her - David Bowie can. :). I love the song, and it looks like this year will be another battle between Lady Gaga and Kylie Minogue.
