Back in March, rapper Wiz Khalifa released his gold-selling LP, entitled Rolling Papers. The disc debuted at #2 on the Billboard 200 chart, selling over 197,000 copies in the first week. The Pittsburgh native is already working on his new album. “Yeah, I’ve started working on a next album just to get a feel for where I’m going with it,” Wiz told MTV News on the BMI Urban Awards red carpet last month. Khalifa also announced that “No Sleep” is the fourth single off the album.
