Pharrell Williams has every reason to be in high spirits following his Grammy wins earlier in the week and it seems as though his good mood is infectious with his single ‘Happy’ finding itself top of the chart once again this week.

Pitbull and Keisha’s collaboration has another strong week holding strong at No. 2. Will.i.am is in at No. 3 with ‘Feelin’ Myself’, his hook-up with Miley Cyrus. ‘Rather Be’ by Clean Bandit featuring Jess Glynn has surged up the chart this week to No. 4. Meanwhile, Avicii slips two place to No. 5 with ‘Hey Brother’.

The rest of the top ten is made up of Hozier, who is at No. 6 an impressive 13 weeks after the release of ‘Take Me To Church’. ‘How Long Will I Love You’ by Ellie Goulding is at No.7, Jason Derulo’s ‘Trumpets’ is just behind her at No.8 while ‘Stay the Night’ Zedd featuring Haylie Williams and Eminem and Rihanna’s ‘The Monster close out the Top Ten.
