Gaga fans shouldn't worry about LFN.
They should worry about how TEOG performs irrespective of the other songs around it.
TEOG will not be able to compete w/ LFN. Gaga can't compete w/ Dr Luke. If you recall, even her most iconic, career-defining, praised, award-winning song (BR) couldn't compete w/ Dr Luke.
But if you look at how BR performed, irrespective of the other songs (that blocked it

) on the charts, it did amazing.
