Mark your calendars, B.o.B fans, because you can expect to hear his sophomore album, Strange Clouds, on March 13. At least, that's the Atlanta rapper revealed this morning on his Twitter account with the following message: "#StrangeClouds Droppin' March 13th!!!!!!!!!" The album will serve as the follow-up to his 2010 debut, The Adventures of Bobby Ray.
