The file identifier refers to a high-quality, lossless digital archive of the 20th Anniversary Edition. The "Soup" tag indicates a curated release by a known quality-control group, and "Updated" suggests a rectified version of an earlier digital leak or release.
There was no guitar feedback. There was no drum stick count-in.
While this release offers the "definitive" version of the Butch Vig remix/remaster in terms of file integrity, listeners seeking the original dynamic range of the album should seek the original 1991 "DGC" mastering or the Mobile Fidelity Sound Lab (MFSL) releases, rather than the 2011 remaster.
