My instinct says to me that I need to say ''Telephone'' because Bey is in it. But I will choose ''Bad Romance'' that song was just amazing from the beginning till the end. Her performances for this song were also good. I just loved this song and I'm mad that it didn't went #1 on the BB Hot 100.
You must agree she changed everything with TFM, I know it was another project and it wasn't about the Fame anymore. But I do agree that she was very sexy with The Fame and when TFM came she was still sexy but not as sexy as in The Fame.
