It just seems ridiculous. Katy Perry's last album set or tied the record for most #1 singles from an album but hasn't even sold close to Adele. I know in this day and age singles can't directly correlate to total album sales but you have to assume there would be some correlation.
Also, if your username is a Sigur Ros reference, nice. Takk...is one of my favorite records.
I know I am WAY late on this, but yes it is a Sigur Ros reference. I love them so freaking much.
