Please send me links

I am looking for good sources of mixtapes and podcasts.  If you read this thing at all you probably know what kind of music I like, but looking for good hip hop, R&B, and new music of any sorts.  Have been listening to my same old ish for a while now and would love some suggestions on ways of hearing new music.  There has to be some good blogs or podcasts to check out.  Let me know.  Thanks!
