yeah i think party starter will be bigger than switch. Switch was kinda like a slap in the face to get people to wake up to whats wills doing. Now hopefully switch has shown those dumb radio stations that people want to hear Will since they all bought the record.
Then with more promo its gotta be a huge hit, it can be suited for more pop/rap people (sorry to have to go there lol) and even the gansta rap fans will like it bcoz of ludas beat. Then when its time to release tell me why, its over! Lost and found will sell like crazy. Thats my prediction anyway, what can i say im an optimistic person.
