75. "Last Christmas" (2007)
Tay does the Wham! legacy proud – she should have also covered "Wake Me Up Before You Go-Go." The ache and quaver of her voice fit the George Michael melancholy; this might be the saddest "Last Christmas" since the original. Plenty of us communed with this version on Christmas 2016, the night we said goodbye to the guy who wrote it. R.I.P., George Michael.
Best line: "A girl on a cover but you tore her apart."
