The fact that she can't get her video out is not good. Has she fulfilled all her obligations in her contract to Interscope? I wouldn't be too surprised if they sever ties this year. I know those label lashings must be too real now.
Like...the era is done...
Rerelease+ EP or get on to the next one
No re-release! Anything with the name ARTPOP isn't going to sell. We'll still need another era to be 100% sure nothing with the name Gaga will ever sell again.
She could pump out another album later this year. But I honestly don't know if it's the music or Gaga herself that turn people away. I've kinda come to the conclusion that it's probably the latter, so there's not much more she can do.
