It was hard to escape Ariana Grande's powerhouse voice this past year -- maybe because she worked with every single person in the world in 2014. Yup, Ari collaborated with everyone from her boyfriend, Big Sean, to Nicki Minaj -- twice! Not to mention those ubiquitous cat ears...

From hooking up with Jessie J and Nicki on "Bang Bang," to teaming up with Major Lazer on "Hunger Games" soundtrack contribution "All My Love," to pairing up with everyone from The Weeknd and Childish Gambino for her own record, My Everything, there were very few artists left untouched by Grande's golden pipes over the past 365 days.

Rank your favorites below, then hit up the comments to let us know who you hope Ari will work with in 2015. (Personally, we're pushing for a hookup between Grande and someone whose name rhymes with Gee-oncé.)
