On the Radio 1 playlist, Magic will still be on the B list for next week too. Very odd, I am 100% sure they are planning to have it on the A list for a while after even the album is released but not sure how that is going to work as the next single will be out before then.
I reckon Magic will get a massive PR push once the video comes out. Its a song that has huge chart potential like Paradise (well the UK charts anyway)
Kworb is amazing btw, best source for Itunes chart info.
