Be serious, Leona has sold nearly two million albums in the UK alone, most of the fans have the album and the rest probably downloaded it illegally, so wont buy the single & the physical for BIT/FITS was £3.99 which is quite pricey for a single so some opted for the album and the album has gone to No.4 again in the album charts and has been for two weeks.
So y'know it wasn't really a flop + it was only 302 copies away from being number 1 and rightfully should have been but the sales for FITS weren't counted towards BIT/FITS only downloads for BIT and physical sales counted, which meant FITS charted in the top 30 on its own, so if they were added together it would have hit the top spot!
