Taylor Swift shows off her voice with performances of 'Lover' and 'False God'

Taylor Swift used her performances on "Saturday Night Live" to showcase her voice. And her numerous green articles of clothing.

The pop superstar served as musical guest for the second episode of the season, which meant she got to play two songs.

First up: "Lover." In contrast to her much-flashier VMAs rendition of the title track of her new album, Swift sat solo at the piano for the song. The singer was decked out in a green turtleneck, green pants, green earrings, green nail polish and at a green piano with a green floor and green walls to look like a scene out of her kaleidoscopic "Lover" music video. Sheet music appeared as if it were frozen midair while Swift tickled the ivories and sang her romantic tune, smiling while cooing lines like "I take this magnetic force of a man to be my lover.

She ended the song with a huge grin and a celebratory shimmy from her (green) piano bench.

Song No. 2: "False God." Swift's live debut of the song was vibey, with a saxophonist, drummer and background singers. Swift and her voice were front and center, though, as she sang and snaked her mic-free arm while wearing black sequined pants and an oversized black blazer. All around her, bare light bulbs shone and smoke rose from the floor.

The stripped-down songs had Twitter buzzing: The hashtag #TaylorOnSNL continued to trend even after "SNL" ended.
