Taylor Swift is trademarking "This Sick Beat"
These include "Party Like It's 1989" (not to be confused with "Party Like It's 1999", "Party Like It's 2033" or "Party Like It's 1699!"), the grammatically cute "Cause We Never Go Out Of Style" and "Nice to Meet You. Where You Been?", and "This Sick Beat" (from "Shake It Off.")
Though not widely known for dropping said beats, if approved, the trademark registration would allow Taylor Swift™ and only Taylor Swift™ to put "This Sick Beat" all over a range of commercial items, including but not limited to:
Accessories for mobile telephones
Removable tattoo transfers
...and more. These sick wind chimes, though.
