Reliable rap charts?

Me and you have the same problem. I like a lot of mainstream artists such as Chamillionaire, Jeezy, Ludacris, Rick Ross ect. but for the most part I listen to underground guys like K-Rino, Lord Infamous, old school Three 6 Mafia/HCP, and Houston mixtapes.

Theultimatecdlink.com is good but sometimes they'll go for a while without updating their charts but for the most parts it is a good sight. They have rap charts, hip-hop news, and it is by far the best sight for rap release dates and CD covers that I have seen. Pretty good sight
