Orgy In Rhythm is a great little Jazz album blog. You’ll definately get excited if you are a crate digger with an appreciation for good music. Lots of great hip hop samples and breaks people!
Sampleur – Sample is a great place to hear original samples alongside the recent hits that sampled them.
Palms Out Sounds has got me open on Sample Wednesdays.
I don’t necessarily agree that the efforts of crate digging mixtapes artists should be given away, but Masscorporation makes very frequent drops of some crazy hot sample mixes by well know diggers.
