“Treat You Better” serves as the lead single for Shawn Mendes' second studio album. The single released on June 3, 2016. The song rocketed up the iTunes charts to number 3 within hours of release, in part, due to Shawn’s #BetteroniTunes drive, encouraging fans to buy it directly from the Apple service.
Lyrically, Mendes sings to his romantic interest, promising to be a better boyfriend than the one she currently has. There was some speculation that this song was about Camila Cabello .
