Artists Pharrell Williams and Bruce Springsteen may be world's apart when it comes to music genres but their popularity is of equal strength as they secure the week's biggest selling single and album respectively.
Multi-talented instrumentalist and vocalist Williams remained in pole position with his feel-good hit Happy, while legendary rock star Springsteen - known as The Boss - usurped Brit songstress Ellie Goulding in the album charts with his latest long-player, High Hopes.
It was a second consecutive week at the top for Williams and the track, capping a fine week in which it was nominated for an Oscar having featured on the soundtrack of the animated movie Despicable Me 2.
The record has now passed 500,000 sales since it made its debut at number 71 at the end of November, coinciding with the film's release.
Williams's grip on the number one spot went relatively unchallenged, with little movement inside the singles top 10.
It meant former chart-topper Timber, by Pitbull featuring Kesha, had to settle for the runner-up spot again.
Avicii and Jason DeRulo remained in third and fourth respectively.
The only new entry inside the top 10 was Do It All Over Again by teenager Elyar Fox, dubbed the UK's answer to Justin Bieber.
Springsteen's 18th studio album dislodged Goulding's Halcyon from the top spot.
High Hopes was the only new entry in the top 20, in a relatively stagnant week in the UK charts, becoming his tenth chart topping album on UK shores.
