A decade or two ago when the labels were doing large-scale analog master tape preservation (mass-digitizing multitrack masters, among others), it was evidently impossible for them to keep their new, Napster-raised generations of engineers' sticky fingers off the files being generated. Because massive collections of high quality multitracks (some I saw topped out in the hundreds of gigabytes to terabytes) began hitting KickAssTorrents and other bittorrent indexes. When you loaded those up in your favorite DAW, you got to hear most songs all the ways to their natural endings -- no fades.
