>>34175936On Billboard's Top 100 Download Albums it charted for 37 weeks straight after release (There seems to have been a slew of new releases in June that pushed it off). After that it fell off the chart again early this month before rising up again last week, meaning it charted for 49/52 weeks during its first year.
Also, 21/52 weeks on the Top Albums Sales chart which I think is about physical sales only, last time it appeared was on May 25th. As it sold out on the first week, it fell off the chart immediately. On Hot Albums (which combines both along with radio play etc.) it was for 26/52 weeks, last appearing on May 18th. It stayed on the chart continuously for 8 weeks after release.
