Radio 2 (the most popular radio station in the UK) has just announced their new playlist (for 5th Jan). THPGU is on the B-list.
Should be enough exposure to get it into the top 20. Will probably need to go up to the A-list tho to make the top 10 (You Have Killed Me and FOTG both reached the A list).
It's on 6 Music's playlist too. It's been left off Radio 1 (quelle surprise!) and I don't think Virgin have added it to theirs...
