Gaga, Charli, Iggy, Meghan Trainor gotta think about it

Lady Gaga: she performed for the Miss Universe contest in my country, and it was before JD hit the chart

fun.: a song from their first album (before We Are Young and the Some Nights album) was used in this music game, which made me notice and like them.

Lorde: Someone here made a thread about her and Royals, and it was long before the song made any impact.
