a big factor in getting on to radio is just catchyness, PS is not as catchy as Switch and so I doubt it will do top 10, more a top 20 single...wills top 4 most successful have been 1. Gettign jiggy with it 1. Switch(Yay), 3 Just the two of us and 4 Miami...(i've done my research lol)..
now..PS it's a better song, has much more relevant lyrics, but how will the market that's dominated by under 14's understand this..
the video though is what potentially can bring it up to switch's level, but i doubt it, i mean the “Looking for the one to be with me” video for instance is probably my favourite will video, but where did it end up in the charts?..
anyway it deserves to be better then switch, but dont get your hopes up too much..
