For the week beginning Saturday 4th March BBC Radio 2 have selected Cloud 9 to be their "Record of the Week". They have also added the single to their "A" playlist, meaning that the track will be played around 20 times in the coming week. It may get a few more plays as it's their 'Record of the Week' as well.
As far as I am aware the last time Jamiroquai were on a BBC Radio playlist was in January 2011 when Lifeline was added to the BBC Radio 2 "C" playlist. In October 2005 (yes, over 11 years ago!) Give Hate A Chance was on the BBC Radio 1 "A" playlist - the last time I believe Jamiroquai was on an "A" list at the BBC.
This addition to the playlist may give the single a chance of getting into the UK top 100 charts. We'll have to wait and see.
