Except Gaga hasn't abandoned her music career (yet at least)
Last album: Rihanna January 2016 // Lady Gaga May 2020
Last concert: Rihanna August 2016 // Lady Gaga February 2020
I agree with your point overall, but I just wanted to point saying theyre both in the same level of "abandoning music" is a massive stretch. However, worrying about Gaga's future looking like that is a valid concert, but she's not there yet (and I don't think she will ever be)
