I use them to learn how a track is made. It's interesting to hear the total breakdown of a production and understand how ever subtle instruments and sequences are, when compiled, it can be an integral piece. They teach us what an artist was thinking while preparing or writing their track.

Everything i've ever collected i've shared so other people can learn and understand music a little more. If everyone did the same instead of using resources as a bargaining chip there would be more enthusiasts and producers with a greater knowledge of music production.
