Charlie Puth is no stranger to the upper reaches of the Irish singles chart - he contributed vocals to Wiz Khalifa's 'See You Again', which enjoyed an extended stay at the top of the rundown this summer.
Now, he's at the top in his own right, with 'Marvin Gaye'. The track, which features another former chart-topper in Meghan Trainor, has leapt straight in at the summit.
It's followed by one of the week's biggest climbers; The Weeknd claims No. 2 with 'Can't Feel My Face'. Lost Frequencies slips to No. 3 with 'Are You With Me', while last week's bestsellers One Direction fall to No. 6.
The collaboration between Calvin Harris and Disciples fares better, as 'How Deep Is Your Love' climbs seven spots to No. 5, while Walk The Moon, Little Mix and Avicii all toast another week in the top ten.
