Exactly how is she declining? Other people gaining does not equate to her decline. If you look at the subs to views ratio, Gaga has one of the best. She has less subs than Katy, Taylor, and Nicki, yet has more views than all of them and is the second female behind Rihanna. What good are subs if they don't translate to views, aka money?
Some of Gaga's own fans act like haters. Always taking things out of context to bring her down. She hasn't released anything in over a year and the other girls still can't reach her view count? Impressive.
