Hard to tell, if she's smart enough and ambitious like Madonna she can. But it's all up to her, she loves to make music so I see her lasting many years.
This is an indeterminate question, a 30 year prediction is not doable. Odds say no, though, it's very unlikely for 99.999...% of artists to reach that level of commercially successful longevity.
She might have huge ticket sales, but she ain't as popular as she was with TFM. I don't think she can pull 30 years of career.
I think she already is fading (compared to her sucess in 2010 let's say).
I would love for her to last long so I could someday look back in my life, and say my generation witnessed the rise of a legitimate superstar. Like someone said on the first page, if she plays her cards right, with that kind of talent, versatility and passion, SHE COULD LAST LONG. She has so much potential, and hers is not just confined to pop music. Someday, when she's older, she could go to jazz, or the fashion industry, or the movies! It's very scary though, given her megasuccess...only a few people get out of it alive. You know, drugs, alcohol, sex... If she stays true to her soul and remains grounded I can see her standing in the spotlight for years to come.
