He released an album called "The Cool" that proved to be another hit for him through two strong singles called "Dumb It Down" and "Superstar". The latter in particular has been a chart climber since it was released in December 2007. It peaked at number 10 on Billboard Hot 100. In the end of 2007, just after only releasing two studio albums, the rapper came with a shocking news that he was about to end his career in music.
"I'm just wearing down," he said. "I'm never doing mixtapes again, not even Internet ones. My whole energy for making hip-hop music is slowing down. I've been doing it for seven years. I still don't think I'm famous. I'll do what I have to do to promote my next album, but I'm not enthused about doing seven albums. I'll do my three, and then I am going to keep moving to the next phase of life and maybe grow trees." Read more about Lupe Fiasco here.
