On Wednesday morning, Billboard's Chart Alert column was running a story claiming that, in the closest race for number one since SoundScan began tracking data in 1991, "The Game's LAX beats Slipknot's All Hope Is Gone by a mere handful of units." It went on to say that the former sold 238,285 copies, the latter 238,272. The margin: a mere 13 copies, or 0.005%.
Twelve hours later, the story had been re-written, with Slipknot's album now adjudged the bigger seller, "barely (winning) out over LAX, moving 239,516 copies...1,134 more than the rapper's 238,382.
Somewhere along the way, errors were detected in the data, and the chart re-run but the margin for error was small, and the records flipped.
Chart re-runs are nothing new - we have had our own share of them here, the most notorious being in 1976, when Manuel & The Music Of The Mountains' recording of Rodrigo's Guitar Concerto was announced as the new number one single, only for the former incumbent, The Four Seasons' December 1963, to be restored to pole position a few hours later because of a "computer glitch" - but Billboard undoubtedly suffered some embarrassment from the error.
So, it's a first ever number one for hard rock heroes Slipknot and not the third number one for The Game.
Also new to the Top 10 are a Now! spin-off that hasn't been tried here - the very first Now! That's What I Call Country arrives at number seven on sales of 50,000 - and Solange's Sol-Angel & The Hadley Street Dreams, debuting at number nine on sales of 46,000.
Of 25 new entries in total, three are by British acts. Dragonforce debut at number 18 with Ultra Beatdown on sales of 24,000 copies; The Verve's Forth debuts at number 23 on sales of 21,000; and Motorhead's Motorizer earns a number 82 slot from sales of 6,500.
The Verve's last album, Urban Hymns, is their only previous chart entry, and also reached number 23, in 1997. Metal band Dragonforce have also had just one previous chart entry, reaching number 103 last year with Inhuman Rampage.
Motorhead - actually an Anglo/Swedish alliance these days - have had five previous Top 200 entries, the first being Iron Fist in 1982, the last 1916, confusingly, in 1991. The latter album provided the group's previous highest placing, reaching number 142.
Coldplay's Viva La Vida Or Death And All His Friends continues to be the top UK album, rebounding 11-10 on sales of 44,000, while their Viva La Vida single continues at number seven on the Hot 100.
Leona Lewis' Spirit - originally listed as a non-mover at number 18 but shuffled down to 19 on the chart re-run - sold 24,000 copies to increase its career tally to 1,042,000.
In the lower regions of the chart, Led Zeppelin's Mothership makes the most impressive upwards progress, vaulting 142-88 on its 42nd week in the chart. The album, which peaked at number seven last year, has sold 966,000 copies, including 6,000 last week. Its sudden lurch back into the top half of the chart is due to sales of the newly-issued deluxe four LP vinyl version of the set.
On the Hot 100, T.I.'s Whatever You Like continues at number one but faces a tough battle against Pink, whose So What leaps 9-3.
The top UK act on the list is M.I.A., whose Paper Planes glides 6-5, a move fuelled by increased airplay, though its sales are off from 124,000 to 114,000. Leona Lewis's Better In Time also suffers a minor sales slip but still climbs 22-19 on the download chart and 28-22 on the Hot 100.
Finally, Natasha Bedingfield's Pocketful Of Sunshine holds at number 30 on the Hot 100, while reversing 39-43 on the download chart - but the 27,000 copies it sold last week bring up its two millionth sale in total. Her album of the same name climbs 72-64, with sales of 8,000 lifting its to-date tally to 404,000.
