She's right. She isn't saying the album was her best selling one or that she didn't had it rough this era, but she's saying that the album succeded at least in inspiring people. The media was after her the moment Applause dropped until SWSX and you can't deny it, everyone wanted to make her look unsuccessful.
She may be trying it a bit with the "contemporary art rave and love" tho

And I doubt anyone knows what Twista is saying in his JnD verse or what language is Gaga speaking during Donatella's chorus.
