BBC tease

PUT SOME ENGLISH ON IT: Keep calm and carry on, lovey; we've got the playlisted tracks and rotation increases at BBC Radio 1. We note the arrival of Aussie Pop sensations 5 Seconds of Summer and the A-Listing of Avicii, John Newman, Kings of Leon and pop-rocking kids The Vamps, who've also seen big jumps at Shazam. (3/26p)
