Then in the first stanza of Lady Gaga's song, the intonation of her voice is very much like the intonation Bowie used in his album "Hours". I'm not a fan of Lady Gaga, but I do like a few of her songs like "Bad Romance" because it was different. The concept of "Applause" just reminds me of Bowie's song "Fame". She is using too many Bowie elements so that she is not influenced by him, but copying.
Here is "Applause" : http://www.youtube.com/watch?v=_bHhpufKRjs
