Will.i.am & Britney Spears continue their ascent up the Irish singles chart this week, with 'Scream & Shout' knocking James Arthur's 'Impossible' from the No.1 perch. The X-Factor winner hasn't had too far to fall though, he's at No.2.

Lumineers hang on to third place with 'Ho Hey', with Rihanna Feat. Mikky Ekko's 'Stay' and Taylor Swift's 'I Knew You Were Trouble' switching places at No.4 and 5 respectively.

This weeks chart features no less than nine new entries; the highest being 50 Cent, who enters at No.6 with 'My Life' which also features Eminem and Adam Levine.

One Direction ('Kiss You'), Emile Sande ('Clown'), Bruno Mars ('Locked Out Of Heaven') and Calvin Harris feat Tinie Tempah ('Drinking From The Bottle') make up the rest of the top ten.

Surprisingly, Justin Timberlake's comeback single 'Suit & Tie' that features Jay Z only made it to No.16 in it's first week on the chart.

The Script remain the highest Irish entry, 'Hall Of Fame' featuring Will.i.am is down five places to No.26.
