Bella should record an old Kesha demo, like Miranda did with Disgusting. I'd be here for her chart topping versions of Butterscotch, Never Know About Love, or A La Discotheque
I've seen many people say this I've also heard that it's not (and is the final was produced by Luke and Max, like Dirty Love)... I think the "2.0" really is just the album version and the other is the studio demo. It was pretty close to getting on the record after all. Regardless, fanmade or not, that version is better than the other.
Also Shots is definitely not overrated, it really is one of, if not the best unreleased song, and one of her best songs overall. It's just pop perfection. She has more overrated songs than that.
I'll have to give Bella's new song a listen, Call It Whatever was a nice lil bop.
My Top 5 (like many others, is subject to change on a regular basis):
1. Animal
2. Last Goodbye
3. Take It Off
4. C'Mon
5. Backstabber / Shots On The Hood Of My Car / Booty Call
