Well, for me...
1. I
do think she needs Dr. Luke to be successful, unfortunately.
Ke$ha is a character, as we now know, and she does pop music with Dr. Luke.
I don't see her being successful/commercial anymore if she splits from him & tries to be more serious/mature.
I just don't see it happening... it's all just a big mess now.
2. I think she clearly has talent & she can write, but has she actually released anything mature or artistic enough for people to realize this? No. Her albums are filled with fun, trashy [no shade] pop music. You can't really blame the GP for aligning her with the image she & Luke made for her from the very beginning.
3. I can't say I'm a huge fan of what she's released so far. She may have written all of her songs, but they all seem pretty disposable as well, except for a few like "Past Lives". That said, I'm very interested to see what she decides to do next.
