Some of the most common musical moves of 10s pop are put to iconic use in this chapter. We’ve got the cut to near-silence before a full-volume ‘soar’ chorus slams in (“Tik Tok”), the talky, slangy breakdown (“Shake It Off”), the annihilating house-inspired beat (“I Gotta Feeling”) and the instant meme lyrics (all three of these, though the tossed off “Mazel tov” remains my favorite). How will these tropes age? Absurdly, probably, but I predict a nailed “This...sick...beat” will kill at karaoke bars for decades to come.
