Congratulations to Benny Blanco, who claims the Number 1 spot on this week's Official Irish Singles Chart with Eastside.

The track, which features Halsey and Khalid, is the US producer's first single as a named artist, having landed huge hits as a songwriter/producer on tracks including Justin Bieber's Love Yourself and Maroon 5's Moves Like Jagger.
