the afd ended in august but the single didn't hit the charts until october unless billboard's bubbling under r b hip hop singles doesn't qualify as a national music chart then wp band would seem to be satisfied as i noted in my edit summary when i denied the speedy regards talk on further research and that could be the answer billboard's web site says most of the charts in billboard are either pure sales or radio charts the only exceptions in which we mingle sales and radio data are two of our signature charts the billboard hot and hot r b hip hop songs as well as two charts based on the same data feeds as the hot the hot 's bubbling under chart which ranks the top titles that have not yet reached the hot and heatseekers songs which reflects the most popular songs by new or developing acts defined as those who have never appeared as a lead artist in the top of the hot or the top of hot airplay prior to dec doesn't address bubbling under r b hip hop singles chart but the logic is pretty much the same i suspect i think that's enough answer to satisfy me however thanks and sorry to have bothered you tm
