I think a big reason for her to resist a new FM album was her lack of material. Recall at the beginning of the DR doc everyone, including her, talks about how she basically realized she couldn't just show up with all old material when LB was going to have lots of new stuff. She asked for that extra month before starting where she went off and wrote (as she mentioned MULTIPLE times) "FOUR new songs!". It just feels like she wasn't going to be able to muster up that much creativity or discipline to bring anything to a new FM album, especially one where whatever she brought would be up against not only Lindsey's new material but all of Chris's as well. I think she just couldn't keep up and didn't want to have it be super obvious.
