Clean Bandit score a personal best this week as Rockabye becomes the band's longest-running Number 1 single.
The Sean Paul and Anne-Marie featured track today notches up a fifth week at the top of the Official Singles Chart, surpassing the four weeks their former chart-topper Rather Be logged at the summit in 2014.
Combined chart sales of over 70,000 kept Rockabye at Number 1, and also claims the most downloaded (30,000) and most streamed (4.04 million) song of the week.
