Depending on how long his label holds out the single from iTunes and how much airplay and exposure it gets, this song could very well top the Hot 100 but I'm guessing just for a week if anything. Supposing sales and airplay are generally high, I expect Crush to peak between numbers 3-7.
Archie fans are gonna go a-wall voting for it to hit iTunes #1 so i'll expect anywhere in the top 10 then fall after that because radio does not play songs from artists that has to struggle to keep up and sing a midtempo joint
