If any of you are into R&B/Rap and need to keep up with the latest stuff coming out stateside, try checking out
Promo Cartel I haven't received any of their stuff yet, but the concept seems good and it seems they have some good material; but proof is in the pudding as they say, so we'll see if they're as good as they claim.
Additionally another good site for keeping your finger on the pulse for new R&B is
Vibin', check out the 'The Music' link, and then 'New Releases'
Finally, one more good source of info is
Blues & Soul, check out the 'Charts' link, and then click 'The Hip List' link.
Soulfully yours,
Tone
