BL isn't going to withstand its sales loss if they keep it album only. It'll drop to nearly half the overall chart points it would have had previously; Katy and Gaga will plow right through it. Gaga could even get multiple weeks at #1 if this isn't fixed, though I'm not complaining about that.
Perhaps it being album only is a glitch of some sort, but it does make sense that they'd want to use its popularity to shift albums.
