Sam's Bi-Weekly Singles Chart (#4)

Although many may oppose this method, I have decided to introduce a midweek chart, although in reality it’ll just be a second chart of the week, with one on Sunday and the other on Wednesday.

This midweek chart sees a lot of shakes ups, although the one we're all interested in is the number-one spot; now occupied by Wiz Khalifa with "Black and Yellow" which climbs 3-1, pushing down Rihanna (1-2) and Jessie J (2-3) in the process. The top 10 sees climbs from Willow (07-05) and Noah and the Whale (09-07) with new entries from Nicole Scherzinger (09) and The Black Eyed Peas (13-10). All this movement means that poor Taio Cruz and David Guetta are pushed out with "Higher" (06-11) and "Who's That Chick?" (10-13) respectively.

The week's biggest climber comes from Dr. Dre, whose collaborative single with Eminem and Skylar Grey jumps an amazing 24 places to number 16. The silver and bronze medals for the achievement are distributed to Wretch 32 featuring Example and The Vaccines which both experience significant rises with "Unorthodox" (34-23) and "If You Wanna" (20-14) respectively. The week's biggest faller is sadly awarded to Olly Murs with "Heart On My Sleeve" (22-31), with Beady Eye and White Lies sharing second place with "The Roller" (31-38) and "Bigger Than Us" (21-28) respectively.

This week also sees a total of five new entries, the highest of which is ex-Pussycat Doll Nicole Scherzinger, whose follow-up single "Don't Hold Your Breath" debuts at number 9. A certain Britney Spears also makes her way onto the chart with "Till The World Ends", debuting at number 32; with the final three new entries being taken up by Snoop Dogg vs. David Guetta, Chipmunk featuring Keri Hilson and Neon Tress with “Sweat” (37) "In the Air" (39) and "Animal" (40) respectively.
