Clean Bandit have beaten will.i.am and Miley Cyrus to spend a second week at number one in the UK.
Their track 'Rather Be', which features vocals from Jess Glynne, has shifted 137,000 copies over the last seven days to keep hold of the top spot.
Last week, 'Rather Be' sold 163,000 copies to achieve the biggest weekly sale for a January chart-topper since Babylon Zoo's 1996 number one 'Spaceman', which sold 383,000 copies.
"Number 1 for a second week? How amazing!" Clean Bandit's Grace Chatto told OfficialCharts.com. "Thank you SO much to everyone who has bought 'Rather Be', and big ups to Jimmy Napes for the lyrics and Jess Glynne for the wonderful singing.
"We're very happy and can't wait for you all to hear what's coming next!"
will.i.am's 'Feelin' Myself', featuring Miley Cyrus, French Montana and Wiz Khalifa, is a new entry at number two, after selling 97,000 copies.
Previous chart-topper Pharrell Williams drops to number three with 'Happy', while Gorgon City's 'Ready For Your Love', featuring MNEK, is new at four.
Katy B has scored her first top five single since 2011 with 'Crying For No Reason', which debuts at number five.
Pitbull and Ke$ha are at six with 'Timber' and Neon Jungle's 'Braveheart' slips three places to number seven, while Avicii's 'Hey Brother' is down two to number eight.
Beyoncé and Jay Z's 'Drunk in Love' is up to number nine after their performance on last weekend's Grammy Awards. Jason Derulo's 'Trumpets' completes this week's top ten.
Katy Perry's latest single 'Dark Horse' rises to number 19 on this week's countdown, following her performance at last Sunday's (January 26) Grammy Awards.
Chris Malinchak is a new entry at 23 with 'If U Got It', which serves as the follow-up to his number two hit 'So Good To Me'.
'It's Raining Men' by The Weather Girls returns to the charts today at number 31. The re-entry is the result of a Facebook campaign launched in response to recent comments by UKIP councillor David Silvester.
Silvester claimed that the recent floods in the UK are caused by the legalisation of gay marriage.
"I'm incredibly proud of the song getting to 31 in the charts," said one of the campaign's organisers, Darren Pop. "It makes me feel very humbled to be part of a community that will pull together to fight back against bigotry.
"It's very comforting to know that British people will always speak up and challenge comments like David Silvester made."
