So I checked the album pre order for Scotty's second album. The album never went top 100 on itunes when it was for preorder. I read some pages on idolforums to compare Phillip and Scotty. Scotty was doing much much worse than what Phillip is doing and Scotty ended up selling 52,000 first week. Scotty has more of a rabid fanbase though while Phillip does not, so I don't know if it gives us any idea on Phillip.
I hope those grandmas pull through
