I cannot believe The Saturdays have been shunned again despite What About Us selling over 500k and becoming the 13th best single of 2013 and "Dear Darlin" and something by "Disclosure"? are nominated instead?
Neither of those stats are true. For a start, it's only actually sold ~390k in the UK - and 13th best selling? Try around 40th, unless you mean British singles, in which case that "something by Disclosure" and "Dear Darlin" both outsold it. The tracks nominated are the 10 best selling British songs of the year. Personally, I'm not a huge fan of many of them, but it is the fairest way to determine the nominees.
