it's very radio friendly.
i guess it's a good come back song. xtina has been away for some time and this is exactly what she needed to come back and face other pop starts like gaga.
but i don't particularly like it. it's average at best. hopefully the rest of her album is better.
there's a song called "glam" that's rumored to be a modern "vogue". i guess that's something to look forward to.
