I doubt Judas will leak. If it hasn't already, then it'll most likely last 7 days. Gaga, if anything, would be the one to release her own material early.
With BTW (album), maybe it'll be like before TFM came out and only 2 songs will leak. But I really doubt it. I also don't want it to leak way before the album is released - if at all. Gaga seems to be on top of leaks, though, moreso than any other mainstream artist. I'm sure the people that have the songs are keeping it pretty tightly locked - considering how leaks seem to piss off Gaga.
But I'll try my best not to listen to the leaks (if any) until the album is officially out, unless it's Government Hooker. Anything else, then I think I could manage (but I'm sure my curiosity will get the best of me

)
