On one hand you have Gaga haters who seem completely entranced and obsessed with her commercial performance. Threads like this are beat to death and it doesn't take that long for a Google search sis. It's been 3 years since the Artpop era and some of you are still acting brand new
On the other hand I do feel like Lady Gaga has been going at her career wrong for some time now. I think this last era she could have bounced back on the charts. But she failed to cater to her base and she failed back on the flamboyance TOO much.
Remember that Madonna declined ALOT from the Immaculate Collection (30M) to Erotica (7M) and didn't really establish herself to well again till ROL. Sure she had hit singles but she wasn't really the pop queen she once was.
Mariah declined as well, as did Whitney etc. Only Janet really had a steady career path commercially until the SB incident.
I think Gaga can bounce back. She's only 30 she has time and she certainly has the talent.
