It gets disgusting when re-releases, usually in a form of 'the best of X', gets their tracks' lengths reduced, all to make space for a larger number of tracks on that album. The worst such a situation is in the case of Don't Leave Me This Way (Harold Melvin & the Blue Notes) which had a release that cut it to about 5 minutes of its original 10 minutes, effectively getting rid of the most exciting part of that track, the climactic second act. A similar thing happened to Brenda Fassie's Weekend Special whose climax was also mercilessly cut in her Greatest Hits album.
