I hope she doesn't for now! Stop making rumours + suggesting things without acknowledge, creating a record label it's expensive + the team on Interscope is really kind and they respect Gaga's vision.
It makes me sad that Interscope takes so much control over their artists, but in not sure if she would be able to make her own label. Although I think if she ever could it could be better for her in the long run.
Gaga has three more albums to make signed with Interscope, that's her contract and then she is moving on to something more opportunistic. Troy Carter said this in an interview about two years back but I'm not sure if its still the case seen as he is not her manager anymore.
this isn't a good idea for her now, she has support and funding from the label she can't lose it now... well I don't know... by the way Gaga is so brave and a little crazy too she's able to everything
