They are indeed on the playlist. I'll be honest, I remain blissfully unaware of what they sound like, I just play along so long as pop gets a good representation on the station. Otherwise it would literally be Tame Impala x30 and a plethora of indie bands that wont even be remembered in a weeks time.
I championed Solange's 'Losing You' and Ellie Goulding which was quite nice. A lot of the more obvious chart smashes get put up instantly anyway since they got complaints last year that they were playing unpopular music. I've lost more than I've won though, Girls Aloud (not Beautiful Cause You Validate Me and Gave Me a Compliment thankfully), Nelly Furtado's 'Parking Lot' (which got ripped to shreds).
It's fun though.
