The Vamps climb 35 places to number four with Somebody To You, with the British boyband receiving a massive sales boost following the release of a re-recorded version featuring US X Factor star Demi Lovato.
In the album chart, summer festival staple Ed Sheeran's X kept Futurology by veteran rockers the Manic Street Preachers off the top.

Further down the chart Nicola Benedetti's Homecoming entered at 19 to make her the first British classical violinist to crack the UK Top 20 since Vanessa Mae in 1995.
Scottish fiddler Benedetti, who will perform at the opening ceremony of the Commonwealth Games in Glasgow, said: "I am absolutely thrilled to have reached the Top 20, not something a classical artist ever expects.
"This is a deeply personal recording - inspired by Bruch's Scottish Fantasy the project took me deep into the heart of Scottish culture.
"I hope the music, in all its diversity, is providing some uplift and pleasure."
