Blender Apologizes to Morrissey - post by tallboy7

Full disclosure: I work at Blender, if that matters, but the fact is Morrissey belongs on that list, and now is on it.

Apology is here:

"For reasons we can hardly explain without legal counsel, our recent list entitled "The Top 50 Geniuses of Pop Music" was delivered to the Internets with one glaring omission: The Smiths lead singer, solo artist, and indisputable genius, Morrissey. In order to make right a small part of the world he might agree is anything but, we add this entry to our now-definitive list. Sorry, Moz."

Full list of geniuses
