Looking for a quick pub quiz fact or a stat or two to add to your chart geekery credentials? We round up five totally random chart facts of the week.
This week's highest climber within the Top 40 is Anne-Marie, who zooms 19 places up the chart to take Ciao Adios to Number 21. The biggest mover from outside the Top 40 is Maroon 5's Cold feat. Future – it rockets 136 slots to break into the Top 40 for the first time at 32.
This week marks the anniversary of Busted's Who's David going to Number 1. Remember that one? Sure you do. It was their third chart-topper out of four, and lasted one week before it was dispatched by the re-release of the seminal Mysterious Girl from Peter Andre. Amazing.
It looks like a few of you celebrated the track's anniversary (and don't try to tell us otherwise). 20 of you downloaded it this week, while it also notched up 19,975 plays on streaming services.
Take That are a new entry at 13 with Giants, the first single from next album Wonderland. It is only the second time a song featuring the word "giant" has cracked the Top 40 – and the first time wasn't that long ago, either. Kiesza's Giant In My Heart was first, reaching Number 4 in 2014.
Ed Sheeran has three tracks in the Top 5 this week. He's not the first person to do it, but it is rare. The last act to achieve it was Justin Bieber, who showed off by holding the Top 3 positions.
It's pretty much our job to take an interest in what you've been buying this week and we love to dig out a totally random track to see if it's been getting any love. This week, we delved into the archive and picked out Britney Spears' Toxic, which hit Number 1 back in 2004. It seems 149 of you were still interested in the taste of a kiss and wanted to ride – that's how many downloads we counted this week, while plays across streaming services over the last seven days totalled 199,000.
