John will be just fine. His last album opened with extremely low numbers & chart placement, then he had his breakout hit 'All Of Me', and his album was certified Gold at the end of it all. His current single has cracked the top 5 on the R&B charts, the top 10 on the R&B/Hip Hop charts, and has jumped to #23 on the Hot 100. John has never been a huge out-the-box seller, his albums sell over time.
