its a good idea if he doesnt wanna shoot for a no.1.
Kanye's album release will cause an increase in overall record sales for that week. J Cole will sell more units this way, but certainly wont outsell Ye.
i dont think its a bad idea... yeezus will bring fans of hip hop into the stores for sure. i doubt that j cole thinks he will outsell this album but i am sure that he KNOWS this move will bring more attention to his record.
