Where have I heard that before?

Where have I heard this before' is my exploration into popular hip hop songs, the samples that make them, and the songs those samples came from. Some weeks I may play a large collection of different artists, and the original songs their major samples came from; while other weeks I may look into one artist and the collection of artists that have influenced that particular artist. Along the way I'll be providing relevant context to the songs, and any conflict that may have come about in using a particular sample.
